Hi John,
I've attached our liblouis sconscript. However:
* This can't be used stand-alone. Rather, it is called from NVDA's
sconstruct. Therefore, some of the required set up is not included in
this file (although that's probably only a few lines).
* This is written for NVDA, so it outputs files in NVDA specific
directories and only builds the dll, Python bindings and tables. The
tools, documentation, tests, etc. are not handled at all.
* There is one compiler flag specific to Windows, but that is only
because of the way we build NVDA.
* This uses configure.ac and the *.in files used by automake. If you
were moving to scons completely, I'd guess it might be neater to get rid
of these and instead pass compiler defines, though there are a few
exceptions to this.
* Scons in-built support for the Windows SDK tends to break from time to
time (I'm not sure what the current status is), so we have written our
own. I can provide this, though it's currently under the terms of the
GPL (not LGPL).

Hi Jamie,
There has been considerable discussion on the BrailleBlaster list of
SCONS in preparation for the next release. I am also thinking of using
it for liblouisutdml Could you send your SCONS files for liblouis as
attachments to this list? That would help us get started.
Thanks,
John
