Current stuff makes a per-package solution file with absolute paths for referenced project files, hence works no matter where the solution file is. This is a good thing since so far I can't figure out how to get SCons to put the solution file where I want itExplicitly install it in directory pkg\visual-variant (e.g., facilities\Visual-vc90-Debug\facilities.sln).
Added code to define INST_DIR in _setup.bat. Can now run (as well as build) programs like test_Ifile in package xmlBase which depend on this environment variable. The Studio debugger is able to find and display source from facilities as well as xmlBase. But Studio constantly thinks it needs to rebuild things it doesn't actually need to rebuild.
