#  v2x2v300.awk:  Very simple, slow and silly AWK script for converting
#                   resource files of former Gcal versions, i.e. v2.20 and
#                   v2.40, into the style which is used by Gcal-3.00 or newer.
#                   This means, all `%?...' special texts which are obsolete
#                   now by reason Gcal offers the ability of defining an
#                   optional format statement, are converted into their
#                   according equivalents.
