+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. Includes a set of files bits/std_xxxx.h
- that implement the standard headers <xxxx>.
-
- 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
- standard header refers to any of them.
+ Files in HTML and text format that document usage, quirks of the

+ All header files for the C++ library are within this directory,
+ modulo specific runtime-related files that are in the libsupc++

src
- Files that are used in constructing the library, but are not
- installed.
-
- testsuites/17_* to 27_*
- Test programs are here, and may be used to begin to exercise the
- library. Support for "make check" and "make check-install" is
- complete, and runs through all the subdirectories here when this
- command is issued from the build directory. Please note that
- "make check" requires DejaGNU 1.4 or later to be installed. Please
- note that "make check-script" calls the script mkcheck, which
- requires bash, and which may need the paths to bash adjusted to
- work properly, as /bin/bash is assumed.

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:
libio
- Contains the subset of the GNU libio library needed for
- C++. Currently not used.

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