+# Introduction
+
+This document discusses the current state of filtering in libyuv. An emphasis on maximum performance while avoiding memory exceptions, and minimal amount of code/complexity. See future work at end.
+
+# LibYuv Filter Subsampling
+
+There are 2 challenges with subsampling
+
+1. centering of samples, which involves clamping on edges
+2. clipping a source region
+
+Centering depends on scale factor and filter mode.
+
+# Down Sampling
+
+If scaling down, the stepping rate is always src_width / dst_width.
+
+ dx = src_width / dst_width;
+
+e.g. If scaling from 1280x720 to 640x360, the step thru the source will be 2.0, stepping over 2 pixels of source for each pixel of destination.
+
+Centering, depends on filter mode.
+
+*Point* downsampling takes the middle pixel.
+
+ x = dx >> 1;
+
+For odd scale factors (e.g. 3x down) this is exactly the middle. For even scale factors, this rounds up and takes the pixel to the right of center. e.g. scale of 4x down will take pixel 2.
+
+**Bilinear** filter, uses the 2x2 pixels in the middle.
+
+ x = dx / 2 - 0.5;
+
+For odd scale factors (e.g. 3x down) this is exactly the middle, and point sampling is used.
+For even scale factors, this evenly filters the middle 2x2 pixels. e.g. 4x down will filter pixels 1,2 at 50% in both directions.
+
+**Box** filter averages the entire box so sampling starts at 0.
+
+ x = 0;
+
+For a scale factor of 2x down, this is equivalent to bilinear.
+
+# Up Sampling
+
+**Point** upsampling use stepping rate of src_width / dst_width and a starting coordinate of 0.
+
+ x = 0;
+ dx = src_width / dst_width;
+
+e.g. If scaling from 640x360 to 1280x720 the step thru the source will be 0.0, stepping half a pixel of source for each pixel of destination. Each pixel is replicated by the scale factor.
+
+**Bilinear** filter stretches such that the first pixel of source maps to the first pixel of destination, and the last pixel of source maps to the last pixel of destination.
+
+ x = 0;
+ dx = (src_width - 1) / (dst_width - 1);
+
+This method is not technically correct, and will likely change in the future.
+
+* It is inconsistent with the bilinear down sampler. The same method could be used for down sampling, and then it would be more reversible, but that would prevent specialized 2x down sampling.
+* Although centered, the image is slightly magnified.
+* The filtering was changed in early 2013 - previously it used:
+
+ x = 0;
+ dx = (src_width - 1) / (dst_width - 1);
+
+Which is the correct scale factor, but shifted the image left, and extruded the last pixel. The reason for the change was to remove the extruding code from the low level row functions, allowing 3 functions to sshare the same row functions - ARGBScale, I420Scale, and ARGBInterpolate. Then the one function was ported to many cpu variations: SSE2, SSSE3, AVX2, Neon and 'Any' version for any number of pixels and alignment. The function is also specialized for 0,25,50,75%.
+
+The above goes still has the potential to read the last pixel 100% and last pixel + 1 0%, which may cause a memory exception. So the left pixel goes to a fraction less than the last pixel, but filters in the minimum amount of it, and the maximum of the last pixel.
+
+ dx = FixedDiv((src_width << 16) - 0x00010001, (dst << 16) - 0x00010000);
+
+**Box** filter for upsampling switches over to Bilinear.

+
+# Future Work
+
+Point sampling should ideally be the same as bilinear, but pixel by pixel, round to nearest neighbor. But as is, it is reversible and exactly matches ffmpeg at all scale factors, both up and down. The scale factor is
+
+ dx = src_width / dst_width;
+
+The step value is centered for down sample:
+
+ x = dx / 2;
+
+Or starts at 0 for upsample.
+
+ x = 0;
+
+Bilinear filtering is currently correct for down sampling, but not for upsampling.
+Upsampling is stretching the first and last pixel of source, to the first and last pixel of destination.
+
+ dx = (src_width - 1) / (dst_width - 1);<br>
+ x = 0;
+
+It should be stretching such that the first pixel is centered in the middle of the scale factor, to match the pixel that would be sampled for down sampling by the same amount. And same on last pixel.
+
+ dx = src_width / dst_width;<br>
+ x = dx / 2 - 0.5;
+
+This would start at -0.5 and go to last pixel + 0.5, sampling 50% from last pixel + 1.
+Then clamping would be needed. On GPUs there are numerous ways to clamp.
+
+1. Clamp the coordinate to the edge of the texture, duplicating the first and last pixel.
+2. Blend with a constant color, such as transparent black. Typically best for fonts.
+3. Mirror the UV coordinate, which is similar to clamping. Good for continuous tone images.
+4. Wrap the coordinate, for texture tiling.
+5. Allow the coordinate to index beyond the image, which may be the correct data if sampling a subimage.
+6. Extrapolate the edge based on the previous pixel. pixel -0.5 is computed from slope of pixel 0 and 1.
+
+Some of these are computational, even for a GPU, which is one reason textures are sometimes limited to power of 2 sizes.
+We do care about the clipping case, where allowing coordinates to become negative and index pixels before the image is the correct data. But normally for simple scaling, we want to clamp to the edge pixel. For example, if bilinear scaling from 3x3 to 30x30, we’d essentially want 10 pixels of each of the original 3 pixels. But we want the original pixels to land in the middle of each 10 pixels, at offsets 5, 15 and 25. There would be filtering between 5 and 15 between the original pixels 0 and 1. And filtering between 15 and 25 from original pixels 1 and 2. The first 5 pixels are clamped to pixel 0 and the last 5 pixels are clamped to pixel 2.
+The easiest way to implement this is copy the original 3 pixels to a buffer, and duplicate the first and last pixels. 0,1,2 becomes 0, 0,1,2, 2. Then implement a filtering without clamping. We call this source extruding. Its only necessary on up sampling, since down sampler will always have valid surrounding pixels.
+Extruding is practical when the image is already copied to a temporary buffer. It could be done to the original image, as long as the original memory is restored, but valgrind and/or memory protection would disallow this, so it requires a memcpy to a temporary buffer, which may hurt performance. The memcpy has a performance advantage, from a cache point of view, that can actually make this technique faster, depending on hardware characteristics.
+Vertical extrusion can be done with a memcpy of the first/last row, or clamping a pointer.
+
+
+The other way to implement clamping is handle the edges with a memset. e.g. Read first source pixel and memset the first 5 pixels. Filter pixels 0,1,2 to 5 to 25. Read last pixel and memset the last 5 pixels. Blur is implemented with this method like this, which has 3 loops per row - left, middle and right.
+
+Box filter is only used for 2x down sample or more. Its based on integer sized boxes. Technically it should be filtered edges, but thats substantially slower (roughly 100x), and at that point you may as well do a cubic filter which is more correct.
+
+Box filter currently sums rows into a row buffer. It does this with
+
+Mirroring will use the same slope as normal, but with a negative.
+The starting coordinate needs to consider the scale factor and filter. e.g. box filter of 30x30 to 3x3 with mirroring would use -10 for step, but x = 20. width (30) - dx.
+
+Step needs to be accurate, so it uses an integer divide. This is as much as 5% of the profile. An approximated divide is substantially faster, but the inaccuracy causes stepping beyond the original image boundaries. 3 general solutions:
+
+1. copy image to buffer with padding. allows for small errors in stepping.
+2. hash the divide, so common values are quickly found.
+3. change api so caller provides the slope.

+
+# The ARGB FOURCC
+
+There are 4 ARGB layouts - ARGB, BGRA, ABGR and RGBA. ARGB is most common by far, used for screen formats, and windows webcam drivers.
+
+The fourcc describes the order of channels in a ***register***.
+
+A fourcc provided by capturer, can be thought of string, e.g. "ARGB".
+
+On little endian machines, as an int, this would have 'A' in the lowest byte. The FOURCC macro reverses the order:
+
+ #define FOURCC(a, b, c, d) (((uint32)(a)) | ((uint32)(b) << 8) | ((uint32)(c) << 16) | ((uint32)(d) << 24))
+
+So the "ARGB" string, read as an uint32, is
+
+ FOURCC_ARGB = FOURCC('A', 'R', 'G', 'B')
+
+If you were to read ARGB pixels as uint32's, the alpha would be in the high byte, and the blue in the lowest byte. In memory, these are stored little endian, so 'B' is first, then 'G', 'R' and 'A' last.
+
+When calling conversion functions, the names match the FOURCC, so in this case it would be I420ToARGB().
+
+All formats can be converted to/from ARGB.
+
+Most 'planar_functions' work on ARGB (e.g. ARGBBlend).
+
+Some are channel order agnostic (e.g. ARGBScale).
+
+Some functions are symmetric (e.g. ARGBToBGRA is the same as BGRAToARGB, so its a macro).
+
+ARGBBlend expects preattenuated ARGB. The R,G,B are premultiplied by alpha. Other functions don't care.

+# Getting Started
+
+How to get and build the libyuv code.
+
+## Pre-requisites
+
+You'll need to have depot tools installed: https://www.chromium.org/developers/how-tos/install-depot-tools
+Refer to chromium instructions for each platform for other prerequisites.
+
+## Getting the Code
+
+Create a working directory, enter it, and run:
+
+ gclient config https://chromium.googlesource.com/libyuv/libyuv
+ gclient sync
+
+
+Then you'll get a .gclient file like:
+
+ solutions = [
+ { "name" : "libyuv",
+ "url" : "https://chromium.googlesource.com/libyuv/libyuv",
+ "deps_file" : "DEPS",
+ "managed" : True,
+ "custom_deps" : {
+ },
+ "safesync_url": "",
+ },
+ ];
+
+
+For iOS add `;target_os=['ios'];` to your OSX .gclient and run `GYP_DEFINES="OS=ios" gclient sync.`
+
+Browse the Git reprository: https://chromium.googlesource.com/libyuv/libyuv/+/master
+
+### Android
+For Android add `;target_os=['android'];` to your Linux .gclient
+
+
+ solutions = [
+ { "name" : "libyuv",
+ "url" : "https://chromium.googlesource.com/libyuv/libyuv",
+ "deps_file" : "DEPS",
+ "managed" : True,
+ "custom_deps" : {
+ },
+ "safesync_url": "",
+ },
+ ];
+ target_os = ["android", "unix"];
+
+Then run:
+
+ export GYP_DEFINES="OS=android"
+ gclient sync
+
+Caveat: Theres an error with Google Play services updates. If you get the error "Your version of the Google Play services library is not up to date", run the following:
+ cd chromium/src
+ ./build/android/play_services/update.py download
+ cd ../..
+
+For Windows the gclient sync must be done from an Administrator command prompt.
+
+The sync will generate native build files for your environment using gyp (Windows: Visual Studio, OSX: XCode, Linux: make). This generation can also be forced manually: `gclient runhooks`
+
+To get just the source (not buildable):
+ git clone https://chromium.googlesource.com/libyuv/libyuv

+# Introduction
+
+Rotation by multiplies of 90 degrees allows mobile devices to rotate webcams from landscape to portrait. The higher level functions ConvertToI420 and ConvertToARGB allow rotation of any format. Optimized functionality is supported for I420, ARGB, NV12 and NV21.
+
+# ConvertToI420
+
+ int ConvertToI420(const uint8* src_frame, size_t src_size,
+ uint8* dst_y, int dst_stride_y,
+ uint8* dst_u, int dst_stride_u,
+ uint8* dst_v, int dst_stride_v,
+ int crop_x, int crop_y,
+ int src_width, int src_height,
+ int crop_width, int crop_height,
+ enum RotationMode rotation,
+ uint32 format);
+
+This function crops, converts, and rotates. You should think of it in that order.
+ * Crops the original image, which is src_width x src_height, to crop_width x crop_height. At this point the image is still not rotated.
+ * Converts the cropped region to I420. Supports inverted source for src_height negative.
+ * Rotates by 90, 180 or 270 degrees.
+The buffer the caller provides should account for rotation. Be especially important to get stride of the destination correct.
+
+e.g.
+640 x 480 NV12 captured<br>
+Crop to 640 x 360<br>
+Rotate by 90 degrees to 360 x 640.<br>
+Caller passes stride of 360 for Y and 360 / 2 for U and V.<br>
+Caller passes crop_width of 640, crop_height of 360.<br>
+
+# ConvertToARGB
+
+ int ConvertToARGB(const uint8* src_frame, size_t src_size,
+ uint8* dst_argb, int dst_stride_argb,
+ int crop_x, int crop_y,
+ int src_width, int src_height,
+ int crop_width, int crop_height,
+ enum RotationMode rotation,
+ uint32 format);
+
+Same as I420, but implementation is less optimized - reads columns and writes rows, 16 bytes at a time.
+
+# I420Rotate
+
+ int I420Rotate(const uint8* src_y, int src_stride_y,
+ const uint8* src_u, int src_stride_u,
+ const uint8* src_v, int src_stride_v,
+ uint8* dst_y, int dst_stride_y,
+ uint8* dst_u, int dst_stride_u,
+ uint8* dst_v, int dst_stride_v,
+ int src_width, int src_height, enum RotationMode mode);
+
+Destination is rotated, so pass dst_stride_y etc that consider rotation.<br>
+Rotate by 180 can be done in place, but 90 and 270 can not.
+
+Implementation (Neon/SSE2) uses 8 x 8 block transpose, so best efficiency is with sizes and pointers that are aligned to 8.
+
+Cropping can be achieved by adjusting the src_y/u/v pointers and src_width, src_height.
+
+Lower level plane functions are provided, allowing other planar formats to be rotated. (e.g. I444)
+
+For other planar YUV formats (I444, I422, I411, I400, NV16, NV24), the planar functions are exposed and can be called directly
+
+
+ // Rotate a plane by 0, 90, 180, or 270.
+ int RotatePlane(const uint8* src, int src_stride,
+ uint8* dst, int dst_stride,
+ int src_width, int src_height, enum RotationMode mode);
+
+# ARGBRotate
+
+ LIBYUV_API
+ int ARGBRotate(const uint8* src_argb, int src_stride_argb,
+ uint8* dst_argb, int dst_stride_argb,
+ int src_width, int src_height, enum RotationMode mode);
+
+Same as I420, but implementation is less optimized - reads columns and writes rows.
+
+Rotate by 90, or any angle, can be achieved using ARGBAffine.
+
+# Mirror - Horizontal Flip
+
+Mirror functions for horizontally flipping an image, which can be useful for 'self view' of a webcam.
+
+ int I420Mirror(const uint8* src_y, int src_stride_y,
+ const uint8* src_u, int src_stride_u,
+ const uint8* src_v, int src_stride_v,
+ uint8* dst_y, int dst_stride_y,
+ uint8* dst_u, int dst_stride_u,
+ uint8* dst_v, int dst_stride_v,
+ int width, int height);
+ int ARGBMirror(const uint8* src_argb, int src_stride_argb,
+ uint8* dst_argb, int dst_stride_argb,
+ int width, int height);
+
+Mirror functionality can also be achieved with the I420Scale and ARGBScale functions by passing negative width and/or height.
+
+# Invert - Vertical Flip
+
+Inverting can be achieved with almost any libyuv function by passing a negative source height.
+
+I420Mirror and ARGBMirror can also be used to rotate by 180 degrees by passing a negative height.

+symlinks to files and directories. This script handles the setup of symlinks to
+achieve this.
+
+It also handles cleanup of the legacy Subversion-based approach that was used
+before Chrome switched over their master repo from Subversion to Git.

+Description:
+The gflags package contains a library that implements commandline
+flags processing. As such it's a replacement for getopt(). It has
+increased flexibility, including built-in support for C++ types like
+string, and the ability to define flags in the source file in which
+they're used.
+
+Local Modifications: None
+
+
+How to update platform configuration files:
+The gen/ directory contains pre-generated configuration header files.
+Historically, all operating systems and architectures have generated
+similar configurations except for Windows. This is why there's only
+posix and win directories below gen/.
+When rolling gflags to a newer version, it's a good idea to check if
+new configuration files needs to be generated as well.
+Do this by running ./configure in the newly checked out version of
+gflags. Then diff the generated files with the ones below gen/.
+If you notice a diff, update the files with the updated ones.
+If you suspect platform dependend changes other than Windows, you'll
+have to checkout gflags on the other platforms as well and run
+./configure there too.

+// --- A note about thread-safety:
+//
+// We describe many functions in this routine as being thread-hostile,
+// thread-compatible, or thread-safe. Here are the meanings we use:
+//
+// thread-safe: it is safe for multiple threads to call this routine
+// (or, when referring to a class, methods of this class)
+// concurrently.
+// thread-hostile: it is not safe for multiple threads to call this
+// routine (or methods of this class) concurrently. In gflags,
+// most thread-hostile routines are intended to be called early in,
+// or even before, main() -- that is, before threads are spawned.
+// thread-compatible: it is safe for multiple threads to read from
+// this variable (when applied to variables), or to call const
+// methods of this class (when applied to classes), as long as no
+// other thread is writing to the variable or calling non-const
+// methods of this class.

+// To actually define a flag in a file, use DEFINE_bool,

+// it useful to register a validator with the flag. This ensures that

+// called when you assign the value to the flag directly using the = operator.
+//
+// The validation function should return true if the flag value is valid, and

+// flag, the flag will retain its current value. If it returns false for the

+// Now come the command line flag declaration/definition macros that

+// their global constructor runs before the global constructor here.
+// (Obviously, we can't guarantee the flags will have the correct
+// default value in that case, but at least accessing them is safe.)
+// The only way to do that is have flags point to a static buffer.
+// So we make one, using a union to ensure proper alignment, and
+// then use placement-new to actually set up the flag with the
+// correct default value. In the same vein, we have to worry about
+// flag access in global destructors, so FlagRegisterer has to be
+// careful never to destroy the flag-values it constructs.
+//
+// Note that when we define a flag variable FLAGS_<name>, we also
+// preemptively define a junk variable, FLAGS_no<name>. This is to
+// cause a link-time error if someone tries to define 2 flags with
+// names like "logging" and "nologging". We do this because a bool
+// flag FLAG can be set from the command line to true with a "-FLAG"
+// argument, and to false with a "-noFLAG" argument, and so this can
+// potentially avert confusion.
+//
+// We also put flags into their own namespace. It is purposefully
+// named in an opaque way that people should have trouble typing
+// directly. The idea is that DEFINE puts the flag in the weird
+// namespace, and DECLARE imports the flag from there into the current
+// namespace. The net result is to force people to use DECLARE to get
+// access to a flag, rather than saying "extern bool FLAGS_whatever;"
+// or some such instead. We want this so we can put extra
+// functionality (like sanity-checking) in DECLARE if we want, and
+// make sure it is picked up everywhere.

+// Implement helpful bash-style command line flag completions
+//
+// ** Functional API:
+// HandleCommandLineCompletions() should be called early during
+// program startup, but after command line flag code has been
+// initialized, such as the beginning of HandleCommandLineHelpFlags().
+// It checks the value of the flag --tab_completion_word. If this
+// flag is empty, nothing happens here. If it contains a string,
+// however, then HandleCommandLineCompletions() will hijack the
+// process, attempting to identify the intention behind this
+// completion. Regardless of the outcome of this deduction, the
+// process will be terminated, similar to --helpshort flag
+// handling.
+//
+// ** Overview of Bash completions:
+// Bash can be told to programatically determine completions for the
+// current 'cursor word'. It does this by (in this case) invoking a
+// command with some additional arguments identifying the command
+// being executed, the word being completed, and the previous word
+// (if any). Bash then expects a sequence of output lines to be
+// printed to stdout. If these lines all contain a common prefix
+// longer than the cursor word, bash will replace the cursor word
+// with that common prefix, and display nothing. If there isn't such
+// a common prefix, bash will display the lines in pages using 'more'.
+//
+// ** Strategy taken for command line completions:
+// If we can deduce either the exact flag intended, or a common flag
+// prefix, we'll output exactly that. Otherwise, if information
+// must be displayed to the user, we'll take the opportunity to add
+// some helpful information beyond just the flag name (specifically,
+// we'll include the default flag value and as much of the flag's
+// description as can fit on a single terminal line width, as specified
+// by the flag --tab_completion_columns). Furthermore, we'll try to
+// make bash order the output such that the most useful or relevent
+// flags are the most likely to be shown at the top.
+//
+// ** Additional features:
+// To assist in finding that one really useful flag, substring matching
+// was implemented. Before pressing a <TAB> to get completion for the
+// current word, you can append one or more '?' to the flag to do
+// substring matching. Here's the semantics:
+// --foo<TAB> Show me all flags with names prefixed by 'foo'
+// --foo?<TAB> Show me all flags with 'foo' somewhere in the name
+// --foo??<TAB> Same as prior case, but also search in module
+// definition path for 'foo'
+// --foo???<TAB> Same as prior case, but also search in flag
+// descriptions for 'foo'
+// Finally, we'll trim the output to a relatively small number of
+// flags to keep bash quiet about the verbosity of output. If one
+// really wanted to see all possible matches, appending a '+' to the
+// search word will force the exhaustive list of matches to be printed.
+//
+// ** How to have bash accept completions from a binary:
+// Bash requires that it be informed about each command that programmatic
+// completion should be enabled for. Example addition to a .bashrc
+// file would be (your path to gflags_completions.sh file may differ):
+
+/*
+$ complete -o bashdefault -o default -o nospace -C \
+ '/usr/local/bin/gflags_completions.sh --tab_completion_columns $COLUMNS' \
+ time env binary_name another_binary [...]
+*/
+
+// This would allow the following to work:
+// $ /path/to/binary_name --vmodule<TAB>
+// Or:
+// $ ./bin/path/another_binary --gfs_u<TAB>
+// (etc)
+//
+// Sadly, it appears that bash gives no easy way to force this behavior for
+// all commands. That's where the "time" in the above example comes in.
+// If you haven't specifically added a command to the list of completion
+// supported commands, you can still get completions by prefixing the
+// entire command with "env".
+// $ env /some/brand/new/binary --vmod<TAB>
+// Assuming that "binary" is a newly compiled binary, this should still
+// produce the expected completion output.

+//
+// thread-safe: it is safe for multiple threads to call this routine
+// (or, when referring to a class, methods of this class)
+// concurrently.
+// thread-hostile: it is not safe for multiple threads to call this
+// routine (or methods of this class) concurrently. In gflags,
+// most thread-hostile routines are intended to be called early in,
+// or even before, main() -- that is, before threads are spawned.
+// thread-compatible: it is safe for multiple threads to read from
+// this variable (when applied to variables), or to call const
+// methods of this class (when applied to classes), as long as no
+// other thread is writing to the variable or calling non-const
+// methods of this class.

+// Implement helpful bash-style command line flag completions
+//
+// ** Functional API:
+// HandleCommandLineCompletions() should be called early during
+// program startup, but after command line flag code has been
+// initialized, such as the beginning of HandleCommandLineHelpFlags().
+// It checks the value of the flag --tab_completion_word. If this
+// flag is empty, nothing happens here. If it contains a string,
+// however, then HandleCommandLineCompletions() will hijack the
+// process, attempting to identify the intention behind this
+// completion. Regardless of the outcome of this deduction, the
+// process will be terminated, similar to --helpshort flag
+// handling.
+//
+// ** Overview of Bash completions:
+// Bash can be told to programatically determine completions for the
+// current 'cursor word'. It does this by (in this case) invoking a
+// command with some additional arguments identifying the command
+// being executed, the word being completed, and the previous word
+// (if any). Bash then expects a sequence of output lines to be
+// printed to stdout. If these lines all contain a common prefix
+// longer than the cursor word, bash will replace the cursor word
+// with that common prefix, and display nothing. If there isn't such
+// a common prefix, bash will display the lines in pages using 'more'.
+//
+// ** Strategy taken for command line completions:
+// If we can deduce either the exact flag intended, or a common flag
+// prefix, we'll output exactly that. Otherwise, if information
+// must be displayed to the user, we'll take the opportunity to add
+// some helpful information beyond just the flag name (specifically,
+// we'll include the default flag value and as much of the flag's
+// description as can fit on a single terminal line width, as specified
+// by the flag --tab_completion_columns). Furthermore, we'll try to
+// make bash order the output such that the most useful or relevent
+// flags are the most likely to be shown at the top.
+//
+// ** Additional features:
+// To assist in finding that one really useful flag, substring matching
+// was implemented. Before pressing a <TAB> to get completion for the
+// current word, you can append one or more '?' to the flag to do
+// substring matching. Here's the semantics:
+// --foo<TAB> Show me all flags with names prefixed by 'foo'
+// --foo?<TAB> Show me all flags with 'foo' somewhere in the name
+// --foo??<TAB> Same as prior case, but also search in module
+// definition path for 'foo'
+// --foo???<TAB> Same as prior case, but also search in flag
+// descriptions for 'foo'
+// Finally, we'll trim the output to a relatively small number of
+// flags to keep bash quiet about the verbosity of output. If one
+// really wanted to see all possible matches, appending a '+' to the
+// search word will force the exhaustive list of matches to be printed.
+//
+// ** How to have bash accept completions from a binary:
+// Bash requires that it be informed about each command that programmatic
+// completion should be enabled for. Example addition to a .bashrc
+// file would be (your path to gflags_completions.sh file may differ):
+
+/*
+$ complete -o bashdefault -o default -o nospace -C \
+ '/usr/local/bin/gflags_completions.sh --tab_completion_columns $COLUMNS' \
+ time env binary_name another_binary [...]
+*/
+
+// This would allow the following to work:
+// $ /path/to/binary_name --vmodule<TAB>
+// Or:
+// $ ./bin/path/another_binary --gfs_u<TAB>
+// (etc)
+//
+// Sadly, it appears that bash gives no easy way to force this behavior for
+// all commands. That's where the "time" in the above example comes in.
+// If you haven't specifically added a command to the list of completion
+// supported commands, you can still get completions by prefixing the
+// entire command with "env".
+// $ env /some/brand/new/binary --vmod<TAB>
+// Assuming that "binary" is a newly compiled binary, this should still
+// produce the expected completion output.
