+wcalc (command-line scientific calculator)
+
+Wcalc is a very capable command-line calculator. It has standard
+functions (sin, asinh, and sqrt for example, in either radians or
+degrees), many pre-defined constants (pi, e, c, G, etc.), support
+for using variables, "active" variables, a command history,
+hex/octal/binary input and output, unit conversions, embedded
+comments, and the ability to save history to a file and load it
+from a file. Wcalc evaluates expressions using the standard order of
+operations.
+
+Wcalc uses intuitive expressions. For example, Wcalc will evaluate
+5sin 4!-7*2(4%6)^2 to be -221.96631678.

+# 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.
