gscan2pdf is a GUI to ease the process of producing PDFs from scanned documents. You scan in one or several pages and create a PDF of selected pages. Scanning is handled with SANE via scanimage. PDF conversion is done by PDF::API2. Perl is used for portability and ease of programming, with gtk2-perl for the GUI.
Garbure is a collection of dedicated distributions. Each distribution provides carefully selected tools for a specific target domain, and is completed with examples and documentation. The set of distributions forms an entity, but each distribution works also on its own. All elements are arranged in the same way for each distribution.
