3 # regen.pl - a wrapper that runs all *.pl scripts to to autogenerate files
5 require 5.003; # keep this compatible, an old perl is all we may have before
8 # The idea is to move the regen_headers target out of the Makefile so that
9 # it is possible to rebuild the headers before the Makefile is available.
10 # (and the Makefile is unavailable until after Configure is run, and we may
11 # wish to make a clean source tree but with current headers without running
17 # keep warnings.pl in sync with the CPAN distribution by not requiring core
19 # safer_unlink ("warnings.h", "lib/warnings.pm");
21 # Which scripts to run. Note the ordering: embed.pl must run after
22 # opcode.pl, since it depends on pp.sym, and autodoc.pl should run last as
23 # it reads all *.[ch] files, some of which may have been changed by other
24 # scripts (eg reentr.c)
38 # Which files are (re)generated by each script.
39 # *** We no longer need these values, as the "changed" message is
40 # now generated by regen_lib.pl, so should we just drop them?
