[Scons-users] Shared Versioned Library - SONAME

[Managan, Rob]

AS a person responsible for most of that coding I can say I am not proud
of the result. The variation in shared library naming conventions was much
greater than I realized. As you point out what is in Scons now lacks
flexibility and probably could stand to be rewritten.
