# _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 $(top_srcdir)". When neither is specified, use all files that
# are under version control.
#
# containing | non_containing
#
# Select the files (non) containing strings matching this regexp.
# If both arguments are specified then CONTAINING takes
# precedence.
#
# with_grep_options
#
# Extra options for grep.
#
# ignore_case
#
# Ignore case.
#
# halt
#
# Message to display before to halting execution.
#
# Finally, you may exempt files based on an ERE matching file names.
# For example, to exempt from the sc_space_tab check all files with the
# .diff suffix, set this Make variable:
#
# exclude_file_name_regexp--sc_space_tab = \.diff$
#
# 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.
