+New users may wish to point their web browsers to the file
+documentation.html in the 'docs/html' subdirectory. It contains brief
+building instructions and notes on how to configure the library in
+interesting ways.
Instructions for configuring and building appear in
docs/html/install.html.
It has subdirectories:
docs
- Files in HTML and text format that document usage, quirks of the
- implementation, and contributor checklists.
-
- include/std
- Files meant to be found by #include <name> directives in
- standard-conforming user programs.
-
- include/c
- Headers intended to directly include standard C headers.
- [NB: this can be enabled via --enable-cheaders=c]
-
- include/c_std
- Headers intended to include standard C headers, and put select
- names into the std:: namespace.
- [NB: this is the default, and is the same as --enable-cheaders=c_std]
-
- include/c_shadow
- Headers intended to shadow standard C headers provided by an
- underlying OS or C library, and other headers depended on directly
- by C++ headers (e.g. unistd.h). These are meant to wrap the names
- defined there into the _C_legacy namespace.
- [NB: this can be enabled via --enable-cheaders=c_shadow]
-
- include/bits
- Files included by standard headers and by other files in
- the bits directory.
-
- include/backward
- Headers provided for backward compatibility, such as <iostream.h>.
- They are not used in this library.

- include/ext
- Headers that define extensions to the standard library. No

Other subdirectories contain variant versions of certain files
that are meant to be copied or linked by the configure script.
In addition, three subdirectories are convenience libraries:

Note that glibc also has a bits/ subdirectory. We will either
need to be careful not to collide with names in its bits/

Development tools:
------------------
-You will need a recent version of gcc to compile the snapshot of
-libstdc++. The use of CVS gcc, or gcc-3_0-branch is strongly
-recommended, which may introduce additional dependencies for
-up-to-date binutils. In addition, you may need up-to-date tools for
-modifying Makefiles and regenerating configure scripts: automake
-(version 1.4), autoconf (version 2.13 and higher), and libtool.
