+Extrema is a powerful visualization and data analysis tool that 
+enables researchers to quickly distill their large, complex data sets 
+into meaningful information. Its flexibility, sophistication, and 
+power allow you to easily develop your own commands and create highly 
+customized graphs. 
+
+This requires wxGTK.

+# 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 ':'.
