+ralcgm (view/convert CGM vector image files)
+
+RAL-CGM is a program to translate or interpret CGM (Computer Graphics
+Metafile) files, either to a different encoding (Binary, Character or
+Clear Text) or to view on a terminal or to send to a plotter (PostScript
+or HPGL).
+
+It can be used as an ImageMagick or GraphicsMagick delegate to convert
+from CGM format.
+
+If you want to compile the example code:
+
+gcc -o testcgm -I/usr/include/ralcgm \
+    /usr/doc/ralcgm-3.50/examples/testcgm.c -lcgm -lm -lX11

+# 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.
