Documancer is programmer's documentation browser with fulltext searching. Documancer is programmer's documentation reader for Unix and Windows which has very fast fulltext searching. It has several advantages over using web browser or specialized format-specific viewers (such as info):

* unified access to all documentation formats
* the GUI is better suited for documentation reading that generic web browser
* documancer can create fulltext index for the docs and enables the user to quickly search it
* bookmarks and indexes are manual-specific, which reduces false matches and chaos in bookmarks
