#                              The default (heavily patched) embedded copy should work, or you can
#                              leave it off altogether -- the only public apps that make use of it are
#                              samples and tests, since NCBI's database servers are of course firewalled.

# seems muParser is required, also glew is required. configure exits otherwise if these are explicitly passed to it (due to USE flag enabled)
