# In general, we run help2man to build a man page from the binary's --help
# output, but when building from a just-unpacked distribution tarball, we
# must not do that, since help2man uses perl.  We don't want to depend on
# perl in that case.  In general, the .1 file does indeed depend on the
# binary.  I.e., for cat, we have this Makefile dependency:
#   man/cat.1: src/cat
# That means that once we build src/cat, we would trigger the .x.1
# rule which runs help2man.  The trick is simply to change the RHS to
# "src/cat.c" in the $(distdir) that we're about to tar and compress.
# Also handle the three exceptions corresponding to the three binaries
# for which there is no like-named .c file: dir, vdir, ginstall.
