+libsigc++ implements a typesafe callback system for standard C++. It
+allows you to define signals and to connect those signals to any
+callback function, either global or a member function, regardless
+of whether it is static or virtual.
+
+It also contains adaptor classes for connection of dissimilar
+callbacks and has an ease of use unmatched by other C++ callback
+libraries. Libsigc++ is licensed under the GNU Library General

+# 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 ':'.
