Import Debian changes 3a5-1debian/3a5-1

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).
