Import Debian changes 3a1-4.2debian/3a1-4.2
slib (3a1-4.2) unstable; urgency=low
* Non-maintainer upload.
* Add guile.init.local for use within the build dir, since otherwise we
have an (earlier unnoticed) circular build-dep due to a difference
between scm and guile.
slib (3a1-4.1) unstable; urgency=low
* Non-maintainer upload.
* Build-depend on guile-1.6 instead of scm, since the new version of
scm is wedged in unstable (closes: #281809).
slib (3a1-4) unstable; urgency=low
* Also check for expected creation on slibcat. (Closes: #240096)
slib (3a1-3) unstable; urgency=low
* Also check for /usr/share/guile/1.6/slib before installing for guile
1.6. (Closes: #239267)
slib (3a1-2) unstable; urgency=low
* Add format.scm back into slib until gnucash stops using it.
* Call guile-1.6 new-catalog (Closes: #238231)
slib (3a1-1) unstable; urgency=low
* New upstream release
* Remove Info section from doc-base file (Closes: #186950)

slib (2d4-2) unstable; urgency=low
* Fix url for upstream source (Closes: #144981)
* Fix typo in slib.texi (enquque->enqueue) (Closes: #147475)
* Add build depends.
slib (2d4-1) unstable; urgency=low
* New upstream.
slib (2d3-1) unstable; urgency=low
* New upstream.
* Remove texi2html call in debian/rules. Now done upstream. Add make
html instead.
* Changes to rules and doc-base to conform to upstream html gen
* Clean up upstream makefile to make sure it cleans up after itself.
