+julius -- Re-implementation of Caesar III.
+
+Julius is a fully working open-source version of
+Caesar 3, with the same logic as the original, but
+with some UI enhancements, that can be played on
+multiple platforms.
+
+Julius will not run without the original Caesar 3
+files. You can buy a digital copy from GOG or Steam,
+or you can use an original CD-ROM version.
+
+The goal of the project is to have exactly the same
+game logic as Caesar 3, with the same look and feel.
+This means that the saved games are 100% compatible
+with Caesar 3, and any gameplay bugs present in the
+original Caesar 3 game will also be present in Julius.

+# 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.
