no plugins. * configure.in: Merged the old text from qt/configure.in and libguile/configure.in; Tom Tromey says automake only wants one configure.in script. This seems fishy, but... * Makefile.am: List the subdirectories explicitly; no more PLUGIN gubbish. * acconfig.h, acinclude.m4: Moved here from libguile, since libguile's configure script lives here now. * AUTHORS, INSTALL, README: Updated. * Makefile.in, aclocal.m4 configure: Regenerated. Just like amputated amphibian limbs.
