Import Debian changes 2c7-1debian/2c7-1

slib (2c7-1) unstable; urgency=low

  * New upstream.
  * Add slibconfig back in.

slib (2c6-2) unstable; urgency=low

  * Remove the slib$(VERSION).info file.  Cut the diff back down to
    size. 

slib (2c6-1) unstable; urgency=low

  * New upstream.
  * Move docs to /usr/share. Up standards version. add /usr/doc symlink.
    Move info files.  Remove undocumented link.

slib (2c5-6) unstable; urgency=low

  * Lowercase two vars in yasyn.scm (Fixes bug #37222)

slib (2c5-5) unstable; urgency=low

  * Fix it so string-index isn't defined (now there is a
    strsrch:string-index) (Fixes #38812)

slib (2c5-4) unstable; urgency=low

  * Don't run slibconfig in postinst.  (Fixes bug #38253, #37733, #37715,
    #37746,  #37809, #37917, #38123, #38462)

slib (2c5-3) unstable; urgency=low

  * Run slibconfig in postinst.  It was commented out there, but I don't
    see any old bug reports on why it was commented out, so let's try
    again. :)  (Fixes bug #37221)

slib (2c5-2) unstable; urgency=low

  * Link mklibcat.scm to mklibcat.  Fixes a problem with using slib with
    guile.

  * New upstream.

slib (2c3-4) unstable; urgency=low

  * New maintainer.
