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.
