GNU documentation tree

This is a copy of the GNU Project's documentation tree, suitable for viewing with any WorldWide Web browser. More information is available elsewhere on how this tree was created.

This documentation is also available inside GNU Emacs in the info system, accessible via the keystrokes C-h i, as well as via the standalone xinfo program.

These two interfaces offer more powerful search capabilities, and perhaps also faster display, than most Web browsers. In particular, their search capabilities extend across file boundaries, which no current Web browser can do. Thus, the HTML form of the documentation tree should be regarded as inferior to the info form, even if some users may find a Web browser interface more comfortable.

When you visit any of these locations, you may find it helpful to start by selecting the table-of-contents link at the top of the first page, in order to get oriented.
