FSF pointed out license doesn't allow modified versions to be distributed. * Get a complete list of copyrights that apply to the source into copyright file. * Remove setup for guile 1.3. * Remove postrm. Just calling install-info (lintian) Move install-info call to prerm since doc-base doesn't do install-info. slib (2c9-3) unstable; urgency=low * Change info location to section "The Algorithmic Language Scheme" to match up with where guile puts it's files. * Postinst is running slibconfig now. (Closes: #75891) slib (2c9-2) unstable; urgency=low * Stop installing slibconfig (for guile). * In postinst if /usr/sbin/slibconnfig exists call it (Close: #75843 #75891). slib (2c9-1) unstable; urgency=low * New upstream (Closes: #74760) * replace string-index with strsrch:string-index in http-cgi.scm. * Add doc-base support (Closes: #31163)
