From: Andy Dougherty Date: Wed, 26 Mar 1997 19:27:52 +0000 (-0500) Subject: INSTALL-1.11 X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=a5d126c22eb526701c899be27a05a7d0d93dff97;p=p5sagit%2Fp5-mst-13.2.git INSTALL-1.11 On March 25, I wrote: > I'll try to take various comments into account and eliminate unnecessary > markup in INSTALL. (I will, however, leave in what I consider to be > necessary or useful markup.) Here's a patch to bring you version 1.11 of the INSTALL file. This patch is relative to the version in 5.003_95. By far the biggest part of the patch is removing unnecessary markup in the file. There actually wasn't all that much anyway, but most of it wasn't necessary for clarity, so I just removed it. There are now just 13 uses of C<> and B<>. (These too are debatable, but I have no interest in debating them. I've already decided to keep them for now.) I've included Chip's suggestion about 'splain and diagnostics.pm and added a little more info about the pod format. There are also some minor rewordings here and there, all aiming to enhance clarity. I hope it didn't regress instead :-) At this point, I don't see any reason to include a separate INSTALL.txt version in the distribution. If we want to mv INSTALL INSTALL.pod I won't argue much against it. p5p-msgid: Pine.SOL.3.95q.970326140905.10178A-100000@fractal.lafayette.edu --- diff --git a/INSTALL b/INSTALL index 3376508..1b010da 100644 --- a/INSTALL +++ b/INSTALL @@ -1,15 +1,3 @@ -This document is written in a format called Plain Old Documentation, -or "pod" for short.
