# VMS linker usually expects an explicit object module that contains main().
# Yet on *NIX, the main module can be automatically resolved from a library --
# this may arguably be convenient with dynamic linking, and is also used with
# Boost.Test.
# To handle such cases on VMS, one needs first to locate the library module
# containing main(), then include it in sources for the link command.
# GLOB_ARCHIVE built-in can locate the module name (globbing by symbol MAIN).
# To be able to use its result during jam-parsing stage, we need to execute it
# from a separate jam-file that produces a pre-defined option file for link.
