Import Debian changes 3a2-1debian/3a2-1

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.
