slib (3a2-1) unstable; urgency=low * New upstream release. * Acknowledge NMU. (Closes: #281809) * Makefile: Don't hack Makefile; use rules instead. * debian/rules: Set on make invocations: prefix, htmldir, TEXI2HTML. * debian/rules (clean): Clean more stuff here. * Makefile: Comment out old rule for $(htmldir)slib_toc.html. Instead, specify directly that the texi2html invocation produces that file. * debian/rules (binary-indep): Find web files in slib subdir. * debian/control (Build-Depends-Indep): Go back to using scm.
