Changes since 1.126: +18 -15 lines
Go back to use a variable rather than an array for _LATEST_AUTOMAKE, use versionator eclass to go back to the full version instead, so that it's clear what's going on and other developers don't misread the code. It's only perfect for EAPI >= 0 but it's not broken on EAPI=0 anyway.

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).
