# if no environment is set, try to find one, and source it
# user can override auto-detection via SOLAR_SHELL_ENVIRONMENT
# it is not currently possible to handle corner cases like you have an
# AMD64 linux box, create configure environments for both x86 and x86_64,
# and then expect to auto-detect both.
# use SOLAR_SHELL_ENVIRONMENT in such cases.
