+Gcal is a program for calculating and printing calendars. Gcal displays
+hybrid and proleptic Julian and Gregorian calendar sheets, respectively
+for one month, three months, or a whole year. It also displays eternal
+holiday lists for many countries around the globe, and features a very
+powerful creation of fixed date liststhat can be used for reminding
+purposes. Gcal can calculate various astronomical data and times of the
+Sun and the Moon for pleasure at any location, precisely enough for most
+civil purposes. Gcal supports some other calendar systems, for example,
+the Chinese and Japanese calendars, the Hebrew calendar, and the civil
+Islamic calendar, too.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
