-# Perl script to generate an Inno Setup installer script for
-# Puzzles. This has to be scripted so that it can read gamedesc.txt
-# and automatically adjust to the current available set of puzzles.
-
-# Usage:
-#
-#   $ ./winiss.pl 20140922.sdfsdf gamedesc.txt > puzzles.iss
-#
-# where the first argument is the version number which will be encoded
-# in the installer's version indicators. The first component of that
-# version number will be expected to be a YYYYMMDD-format date.

-# days since an arbitrary epoch. This number is used for the Windows
-# version resource (which wants a monotonic 16-bit integer). The epoch
-# is chosen so that the first build using this date-based mechanism
-# has a higher number than the last build in which that number was
-# derived from a Subversion revision.
