# 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 ':'.

libsigc++: libsigc++ -- The Typesafe Callback Framework for C++
libsigc++: 
libsigc++: libsigc++ implements a typesafe callback system for standard C++.
libsigc++: It allows you to define signals and to connect those signals to 
libsigc++: any callback function, either global or a member function,
libsigc++: regardless of whether it is static or virtual.
libsigc++: 
libsigc++: libsigc++ is used by gtkmm to wrap the GTK+ signal system. It
libsigc++: does not depend on GTK or gtkmm.
