slib (3a5-1) unstable; urgency=low * New upstream release. * slib.texi (Library Catalogs): Repeat change from 3a3-3. * Makefile: Repeat $(htmldir)slib_toc.html changes from 3a2-1. * guile.init: (library-vicinity): Repeat change from 3a4-2. * debian/rules (binary-indep): Don't hide .init files in a separate subdirectory, thus conforming better to the usual slib practice. Put a symlink in place to ease transitions. (Closes: #407370).
