I've written up some documentation about the build system, could I
please have some feedback as to usefulness, style, shape etc?
thanks,

0. Introduction
---------------
The Subversion build system is a bespoke system written by Greg Stein,
which combines standard tools (autoconf, make) with internal scripts
to speed up the compile cycle.
The Subversion build system provides a number of services:
* Download of external packages/dependencies
A shell script, (get-deps.sh) downloads external packages, unpacks
them, and places them in appropriately named directories.
* Platform specific build configuration
Subversion uses the Autoconf package to detect platform specific
features such as presence of C library functions and location of
standard unix utilities. It is invoked using the command
"./configure". The behaviour of this is changed in a number of
places:
Makefile.in
configure.ac
aclocal.m4
build/ac-macros/*.m4
Please see appendix I for a walkthrough of these files.
* Subversion-specific build configuration
Subversion uses an internally-written set of python scripts to
generate lists of targets and dependencies. It is invoked using the
command "./autogen.sh". This command, among other things, calls
gen-make.py, which in turn calls several more python file in
build/generate. The configuration file for this is build.conf and
the output is a file named build-outputs.mk.
Next, configure uses configure.ac, Makefile.in and build-outputs.mk
to generate the Makefile.
Historically, ./configure took a long time to run, and this setup
significantly reduced the compile time for Subversion.
For a full list of files with a short description, see appendix II.
2. Example compile
------------------
svn co https://svn.apache.org/repos/asf/subversion/trunk
cd trunk
./get-deps.sh
./autogen.sh
./configure --enable-maintainer-mode --prefix=/dev/null
make
3. Debugging the build system
-----------------------------
Running configure produces a useful log file in trunk/configure.log.
'remake' (link below) is a very useful tool to help with debugging the
output of 'make' (see section 4 for the manual).
Sample output of remake:
##>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
cd subversion/svn_hello_world && /bin/bash /home/g/trunk/libtool
--tag=CC --silent --mode=link gcc -g -O2 -g -O2 -pthread -rpath
/dev/null/lib -o svn_hello_world

5. Adding components to the build system
------------------------------------------
The following sections step through making minimal additions to the
build system, the examples presents comprise a librabry, a minimal
execturable and a 3rd party package.
6. Adding a library
-------------------
First, the C files which comprise a library:
