(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)
