# Make a shared library.
# Basically do a switch/case depending on the OS and make a shared
# lib conforming to that OS.


# Usage:
#   mklib [options] objects ...
# Options:
#   -o LIBRARY    specifies the name of resulting library ("GL" for example)
#   -major N      specifies major version number (default is 1)
#   -minor N      specifies minor version number (default is 0)
#   -patch N      specifies patch version number (default is 0)
#   -lLIBRARY     specifies a dependency on LIBRARY
#   -LDIR         search in DIR for library dependencies
#   -cplusplus    link with C++ runtime
#   -static       make a static library (default is dynamic/shared)
#   -install DIR  move resulting library files to DIR
#   -arch ARCH    override using `uname` to determine architecture
#   -archopt OPT  specify an extra achitecture-specific option OPT
#
# The library name should just be "GL" or "GLU", etc.  The 'lib' prefix
# will be added here if needed, as well as the ".so" or ".a" suffix, etc.
#
# objects should be:  foo.o bar.o etc.o
#
# Environment variables recognized:
#   CC   C compiler command
#   CXX  C++ compiler command
#
