Subject: As autodoc.pl no longer rebuilds repository files, no need to use regen_lib.pl
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=7b73ff9889742cfd1d8c92116386d655caecafb7;p=p5sagit%2Fp5-mst-13.2.git

As autodoc.pl no longer rebuilds repository files, no need to use regen_lib.pl
Refactor the duplicated logic for opening, generating and closing files into
a single output() subroutine.
