# --- The idea ---
#
# Each manual page contains lines of the form
#
#   .\" @function
#
# for each function and macro documented in it.  This program sifts through
# all of the `toplevel' manual pages and creates little manpages which
# include the main text for each of the functions.
#
# The file `links' contains a generated list of little link manpages.  This
# list is used for tidying (on a `make clean'), installing (for `make
# install') and for pruning out old links when they're not needed any more.
