# This Makefile is used exclusively by `xref' to generate and maintain
# cross-reference databases (right now: cscope, ctags, and etags).
#
# By default, the cross-reference is built for all files underneath the
# currrent working directory that match the criteria specified in the
# xref.files rule below, and any files that would also be hauled over as
# part of a `bringover' of the working directory (though this can be
# turned off via the -f flag to `xref').
#
# However, this behavior can be customized in each directory of the build
# tree through the following Makefile macros, if necessary:
#
# XRDIRS: The list of directories to include; defaults to `.'.
# The more interesting directories should be listed earlier.
# XRPRUNE: The list of directories to prune out.
# XRADD: The list of additional filename globs to include.
# XRDEL: The list of additional filename globs to exclude.
# XRINCDIRS: The list of additional include paths, in "foo bar" format.
# XRINCS: The list of additional include paths, in "-Ifoo -Ibar" format.
#
# Note that XRINCDIRS and XRINCS are for specifying header paths that are
# not already included in CPPFLAGS and HDRDIR.
#
# These macros are assumed to be set in a file named `Makefile', but this
# too can be overridden via the -m option to `xref'.
#
# This Makefile should *never* be included by other Makefiles.

# Build the list of files to be included in the cross-reference database.
#
# Please note that:
#
# * Any additional FLG-related source files are in xref.flg.
#
# * We use relative pathnames for the file list; this makes it easier
# to share the resulting cross-reference across machines. We also
# strip the leading './' off of pathnames (if necessary) so that we
# don't trip up vi (since it thinks foo.c and ./foo.c are different
# files).
#
# * We strip out any duplicate file names, being careful not to
# disturb the order of the file list.
#
# * We put all the Makefiles at the end of the file list, since they're
# not really source files and thus can cause problems.
#
# * We otherwise do not sort the file list, since we assume that if
# the order matters, then XRDIRS would've been set so that the more
# important directories are first.
