Test Dependencies

[Eric Lemings]

It seems that most of the tests depend on nothing more than the
C++ standard library and the RWTest library.  Others have some
dependencies that are not so obvious.  Some require the TOPDIR
environment variable defined, some locale tests require the
locales database files, etc.  Can someone outlines these
dependencies in greater detail?  Or is this info documented in
a file somewhere in the distribution?
 
Thanks,
Brad.
