+hexcurse (ncurses-based hex editor)
+
+Hexcurse is a curses-based hex editing utility that can open, edit,
+and save files, editing both the hexadecimal and decimal values. It
+currently supports searching, hex and decimal address output, jumping
+to specified locations in the file, "undo" capabilities, "bolded"
+modifications, EBCDIC mode, and quick keyboard shortcuts to commands.

+# 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.

We recently saw an old tarball of the code floating around the net and thought it would be good to start maintaining the codebase again.
