# libstdc++-v3 Source Documentation

## Documentation Overview

@LEVEL@-level docs, generated @DATE@.

There are two types of documentation for libstdc++-v3. One is the distribution documentation, which can be read online at http://gcc.gnu.org/onlinedocs/libstdc++/documentation.html or offline from docs/html/documentation.html in the library source directory.

The other type is the source documentation, of which this is the first page. Both "user-level" and "maintainer-level" source documentation is produced: user-level docs are for the users of this library. The maint-level docs are for those interested in the underlying workings of the library; they include all the user-level docs plus additional notes and additional classes/functions/etc.

Here are quick links to the pages which we seem to use the most; a full index is at the bottom:

- Compound List
- Alphabetical List
- File List
- Modules

## Generating this file

These HTML pages are automatically generated, along with the man pages. The Makefile rules `'make doxygen'` and `'make doxygen-maint'` in the libstdc++-v3 build directory generates these pages using a tool called, appropriately enough, Doxygen. To learn more about Doxygen, take a look at

The libstdc++-v3 configuration files needed to generate doxygen output are located:

- `docs/doxygen/user.cfg.in`
- `docs/doxygen/run_doxygen`

## libstdc++-v3 doxygen style guide

In general, libstdc++-v3 files should be formatted according to the GNU C++ Coding Standard rules found in the file C++STYLE. Before any doxygen-specific formatting tweaks are made, please try to make sure that the initial formatting is sound.

The formatting guidelines for using libstdc++-v3 with doxygen are still incomplete. There seems to be a marginal preference for the use of Java-Doc style formatting, with the idea that the single-line style (triple-slash) is the least intrusive mechanism for getting libstdc++-v3 documented and cross-referenced while at the same time minimizing disruption to the current formatting. Full documentation of functions (parameter types, return values, etc) will require the slash-splat-splat "extended C" commenting style.
