10 # This eclass is for safely handling autotooled software packages that need to
11 # regenerate their build scripts. All functions will abort in case of errors.

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