# @BLURB: Regenerates auto* build scripts
# @DESCRIPTION:
# This eclass is for safely handling autotooled software packages that need to
# regenerate their build scripts.  All functions will abort in case of errors.

# Note: We require GNU m4, as does autoconf.  So feel free to use any features
# from the GNU version of m4 without worrying about other variants (i.e. BSD).
