Can I have a better document about dependencies and required prerequisites, rather than get the errors from `setup.py --help-commands` and fix them one by one?

C:\work\Bazaar\zzz\subvertpy>set SVN_DEV=C:\work\Bazaar\zzz\subvertpy\SVN_DEV

C:\work\Bazaar\zzz\subvertpy>setup.py --help-commands
Traceback (most recent call last):
  File "C:\work\Bazaar\zzz\subvertpy\setup.py", line 254, in <module>
    (svn_includedirs, svn_libdirs, svn_link_flags, extra_libs) = svn_build_data(
)
  File "C:\work\Bazaar\zzz\subvertpy\setup.py", line 203, in svn_build_data
    "Please set SVN_BDB to the location of the svn BDB packages "
Exception: Please set SVN_BDB to the location of the svn BDB packages - see READ
ME.txt in the SV_DEV dir

Also the last line of error has small typo:

Exception: Please set SVN_BDB to the location of the svn BDB packages - see README.txt in the SV_DEV dir

I think it should be

Exception: Please set SVN_BDB to the location of the svn BDB packages - see README.txt in the SVN_DEV dir
