+Berkeley Logo is a freeware interpreter written by Brian Harvey along with
+several students (Major contributors are Daniel van Blerkom, Khang Dao,
+Michael Katz, Douglas Orleans, and Sanford Owings.) It's available for
+Unix/Linux, MacOS X, Windows - complete with C source code. A version for
+One Laptop Per Child is also available (and also older version - BLogo -
+is available for MS/PC-DOS). If you think Logo is just a graphics language
+for little kids, check out sample programs that should impress you.

+# 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.
