-Git for CVS users

=================
-v0.99.5, Aug 2005
Ok, so you're a CVS user. That's ok, it's a treatable condition, and the
first step to recovery is admitting you have a problem. The fact that
already.
The thing about CVS is that it absolutely sucks as a source control

+manager, and you'll thus be happy with almost anything else. git,
however, may be a bit 'too' different (read: "good") for your taste, and
does a lot of things differently.

tracking 'project' history. This sometimes causes problems if you are
used to doing very strange things in CVS, in particular if you're doing

+things like making branches of just a subset of the project. git can't
track that, since git never tracks things on the level of an individual
file, only on the whole project level.
Second: CVS has the notion of a "repository" as opposed to the thing
that you're actually working in (your working directory, or your
-"checked out tree"). Git does not have that notion at all, and all git
+"checked out tree"). git does not have that notion at all, and all git
working directories 'are' the repositories. However, you can easily
emulate the CVS model by having one special "global repository", which
people can synchronize with. See details later, but in the meantime

CVS archive.

+================
+
+NAME
+----
+git-am - Apply a series of patches in a mailbox
+
+
+SYNOPSIS
+--------
+'git-am' [--signoff] [--dotest=<dir>] [--utf8] [--3way] <mbox>...
+'git-am' [--skip]
+
+DESCRIPTION
+-----------
+Splits mail messages in a mailbox into commit log message,
+authorship information and patches, and applies them to the
+current branch.
+
+OPTIONS
+-------
+--signoff::
+ Add `Signed-off-by:` line to the commit message, using
+ the committer identity of yourself.
+
+--dotest=<dir>::
+ Instead of `.dotest` directory, use <dir> as a working
+ area to store extracted patches.
+
+--utf8, --keep::
+ Pass `--utf8` and `--keep` flags to `git-mailinfo` (see
+ gitlink:git-mailinfo[1]).
+
+--3way::
+ When the patch does not apply cleanly, fall back on
+ 3-way merge, if the patch records the identity of blobs
+ it is supposed to apply to, and we have those blobs
+ locally.
+
+--skip::
+ Skip the current patch. This is only meaningful when
+ restarting an aborted patch.
+
+--interactive::
+ Run interactively, just like git-applymbox.
+
+
+DISCUSSION
+----------
+
+When initially invoking it, you give it names of the mailboxes
+to crunch. Upon seeing the first patch that does not apply, it
+aborts in the middle, just like 'git-applymbox' does. You can
+recover from this in one of two ways:
+
+. skip the current one by re-running the command with '--skip'
+ option.
+
+. hand resolve the conflict in the working directory, run 'git
+ diff HEAD' to extract the merge result into a patch form and
+ replacing the patch part of the message in .dotest directory.
+ After doing this, run `git-reset --hard HEAD` to bring the
+ working tree to the state before half-applying the patch, then
+ re-run the command without any options.
+
+The command refuses to process new mailboxes while `.dotest`
+directory exists, so if you decide to start over from scratch,
+run `rm -f .dotest` before running the command with mailbox
+names.

+=======================
+
+NAME
+----
+git-check-ref-format - Make sure ref name is well formed.
+
+SYNOPSIS
+--------
+'git-check-ref-format' <refname>
+
+DESCRIPTION
+-----------
+Checks if a given 'refname' is acceptable, and exits non-zero if
+it is not.
+
+A reference is used in git to specify branches and tags. A
+branch head is stored under `$GIT_DIR/refs/heads` directory, and
+a tag is stored under `$GIT_DIR/refs/tags` directory. git
+imposes the following rules on how refs are named:
+
+. It could be named hierarchically (i.e. separated with slash
+ `/`), but each of its component cannot begin with a dot `.`;
+
+. It cannot have two consecutive dots `..` anywhere;
+
+. It cannot have ASCII control character (i.e. bytes whose
+ values are lower than \040, or \177 `DEL`), space, tilde `~`,
+ caret `{caret}`, or colon `:` anywhere;
+
+. It cannot end with a slash `/`.
+
+These rules makes it easy for shell script based tools to parse
+refnames, and also avoids ambiguities in certain refname
+expressions (see gitlink:git-rev-parse[1]). Namely:
+
+. double-dot `..` are often used as in `ref1..ref2`, and in some
+ context this notation means `{caret}ref1 ref2` (i.e. not in
+ ref1 and in ref2).
+
+. tilde `~` and caret `{caret}` are used to introduce postfix
+ 'nth parent' and 'peel onion' operation.
+
+. colon `:` is used as in `srcref:dstref` to mean "use srcref\'s
+ value and store it in dstref" in fetch and push operations.

NAME
----
SYNOPSIS
--------
-'git-checkout' [-f] [-b <new_branch>] [<branch>]
+'git-checkout' [-f] [-b <new_branch>] [<branch>] [<paths>...]
DESCRIPTION
-----------
-Updates the index and working tree to reflect the specified branch,
-<branch>. Updates HEAD to be <branch> or, if specified, <new_branch>.
+
+When <paths> are not given, this command switches branches, by
+updating the index and working tree to reflect the specified
+branch, <branch>, and updating HEAD to be <branch> or, if
+specified, <new_branch>.
+
+When <paths> are given, this command does *not* switch
+branches. It updates the named paths in the working tree from
+the index file (i.e. it runs `git-checkout-index -f -u`). In
+this case, `-f` and `-b` options are meaningless and giving
+either of them results in an error. <branch> argument can be
+used to specify a specific tree-ish to update the index for the
+given paths before updating the working tree.
+
OPTIONS
-------
Branch to checkout; may be any object ID that resolves to a
commit. Defaults to HEAD.
+
+EXAMPLE
+-------
+
+The following sequence checks out the `master` branch, reverts
+the `Makefile` to two revisions back, deletes hello.c by
+mistake, and gets it back from the index.
+
+------------
+$ git checkout master
+$ git checkout master~2 Makefile
+$ rm -f hello.c
+$ git checkout hello.c
+------------
+
+If you have an unfortunate branch that is named `hello.c`, the
+last step above would be confused as an instruction to switch to
+that branch. You should instead write:
+
+------------
+$ git checkout -- hello.c

+git-svnimport - Import a SVN repository into git
+
+
+SYNOPSIS
+--------
+'git-svnimport' [ -o <branch-for-HEAD> ] [ -h ] [ -v ] [ -d | -D ]
+ [ -C <GIT_repository> ] [ -i ] [ -u ] [-l limit_nr_changes]
+ [ -b branch_subdir ] [ -t trunk_subdir ] [ -T tag_subdir ]
+ [ -s start_chg ] [ -m ] [ -M regex ]
+ <SVN_repository_URL> [ <path> ]
+
+
+DESCRIPTION
+-----------
+Imports a SVN repository into git. It will either create a new
+repository, or incrementally import into an existing one.
+
+SVN access is done by the SVN:: Perl module.
+
+git-svnimport assumes that SVN repositories are organized into one
+"trunk" directory where the main development happens, "branch/FOO"
+directories for branches, and "/tags/FOO" directories for tags.
+Other subdirectories are ignored.
+
+git-svnimport creates a file ".git/svn2git", which is required for
+incremental SVN imports.
+
+OPTIONS
+-------
+-C <target-dir>::
+ The GIT repository to import to. If the directory doesn't
+ exist, it will be created. Default is the current directory.
+
+-s <start_rev>::
+ Start importing at this SVN change number. The default is 1.
++
+When importing incementally, you might need to edit the .git/svn2git file.
+
+-i::
+ Import-only: don't perform a checkout after importing. This option
+ ensures the working directory and cache remain untouched and will
+ not create them if they do not exist.
+
+-t <trunk_subdir>::
+ Name the SVN trunk. Default "trunk".
+
+-T <tag_subdir>::
+ Name the SVN subdirectory for tags. Default "tags".
+
+-b <branch_subdir>::
+ Name the SVN subdirectory for branches. Default "branches".
+
+-o <branch-for-HEAD>::
+ The 'trunk' branch from SVN is imported to the 'origin' branch within
+ the git repository. Use this option if you want to import into a
+ different branch.
+
+-m::
+ Attempt to detect merges based on the commit message. This option
+ will enable default regexes that try to capture the name source
+ branch name from the commit message.
+
+-M <regex>::
+ Attempt to detect merges based on the commit message with a custom
+ regex. It can be used with -m to also see the default regexes.
+ You must escape forward slashes.
+
+-l <max_num_changes>::
+ Limit the number of SVN changesets we pull before quitting.
+ This option is necessary because the SVN library has serious memory
+ leaks; the recommended value for nontrivial imports is 100.
+
+ git-svnimport will still exit with a zero exit code. You can check
+ the size of the file ".git/svn2git" to determine whether to call
+ the importer again.
+
+-v::
+ Verbosity: let 'svnimport' report what it is doing.
+
+-d::
+ Use direct HTTP requests if possible. The "<path>" argument is used
+ only for retrieving the SVN logs; the path to the contents is
+ included in the SVN log.
+
+-D::
+ Use direct HTTP requests if possible. The "<path>" argument is used
+ for retrieving the logs, as well as for the contents.
++
+There's no safe way to automatically find out which of these options to
+use, so you need to try both. Usually, the one that's wrong will die
+with a 40x error pretty quickly.
+
+<SVN_repository_URL>::
+ The URL of the SVN module you want to import. For local
+ repositories, use "file:///absolute/path".
++
+If you're using the "-d" or "-D" option, this is the URL of the SVN
+repository itself; it usually ends in "/svn".
+
+<SVN_repository_URL>::
+ The URL of the SVN module you want to import. For local
+ repositories, use "file:///absolute/path".
+
+<path>
+ The path to the module you want to check out.
+
+-h::
+ Print a short usage message and exit.
+
+OUTPUT
+------
+If '-v' is specified, the script reports what it is doing.
+
+Otherwise, success is indicated the Unix way, i.e. by simply exiting with
+a zero exit status.

-Unless "-f" is given, the tag must not yet exist in ".git/refs/tags"

-If "-s" or "-a" is passed, the user will be prompted for a tag message.
-and a tag object is created. Otherwise just the SHA1 object
-name of the commit object is written.
+If one of `-a`, `-s`, or `-u <key-id>` is passed, the command
+creates a 'tag' object, and requires the tag message. Unless
+`-m <msg>` is given, an editor is started for the user to type
+in the tag message.
-A GnuPG signed tag object will be created when "-s" is used.
+Otherwise just the SHA1 object name of the commit object is
+written (i.e. an lightweight tag).
+
+A GnuPG signed tag object will be created when `-s` or `-u
+<key-id>` is used. When `-u <key-id>` is not used, the
+committer identity for the current user is used to find the
+GnuPG key for signing.
