-# _sc_search_regexp
-#
-# This macro searches for a given construct in the selected files and
-# then takes some action.
-#
-# Parameters (shell variables):
-#
-# prohibit | require
-#
-# Regular expression (ERE) denoting either a forbidden construct
-# or a required construct. Those arguments are exclusive.
-#
-# exclude
-#
-# Regular expression (ERE) denoting lines to ignore that matched
-# a prohibit construct. For example, this can be used to exclude
-# comments that mention why the nearby code uses an alternative
-# construct instead of the simpler prohibited construct.
-#
-# in_vc_files | in_files
-#
-# grep-E-style regexp selecting the files to check. For in_vc_files,
-# the regexp is used to select matching files from the list of all
-# version-controlled files; for in_files, it's from the names printed
-# by "find $(srcdir)". When neither is specified, use all files that
-# are under version control.
-#
-# containing | non_containing
-#
-# Select the files (non) containing strings matching this regexp.
-# If both arguments are specified then CONTAINING takes
-# precedence.
-#
-# with_grep_options
-#
-# Extra options for grep.
-#
-# ignore_case
-#
-# Ignore case.
-#
-# halt
-#
-# Message to display before to halting execution.
-#
-# Finally, you may exempt files based on an ERE matching file names.
-# For example, to exempt from the sc_space_tab check all files with the
-# .diff suffix, set this Make variable:
-#
-# exclude_file_name_regexp--sc_space_tab = \.diff$
-#
-# Note that while this functionality is mostly inherited via VC_LIST_EXCEPT,
-# when filtering by name via in_files, we explicitly filter out matching
-# names here as well.
-
-# Initialize each, so that envvar settings cannot interfere.
