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) * Remove period from end of description (linda, lintian) * html gen fixed upstream (Closes: #111778) 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.

+@defun make-heap pred<?
+
+Returns a binary heap suitable which can be used for priority queue
+operations.
+@end defun
+
+@defun heap-length heap
+
+Returns the number of elements in @var{heap}.
+@end defun

+@deffn {Procedure} heap-insert! heap item
+
+Inserts @var{item} into @var{heap}. @var{item} can be inserted multiple
+times. The value returned is unspecified.
+@end deffn
+
+@deffn {Procedure} heap-extract-max! heap
+
+Returns the item which is larger than all others according to the
+@var{pred<?} argument to @code{make-heap}. If there are no items in
+@var{heap}, an error is signaled.
