# Make a shared library.
-# Basically do a switch/case depending on the OS and make a shared (or static)
-# library conforming to that OS.
-
-
-# Usage:
-# mklib [options] objects ...
-# Options:
-# -o LIBRARY specifies the name of resulting library
-# ("-o GL" for example, might result in "libGL.so" being made)
-# -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
-# -linker L explicity specify the linker program to use (ex: gcc, g++)
-# Not observed on all systems at this time.
-# -cplusplus link with C++ runtime
-# -static make a static library (default is dynamic/shared)
-# -install DIR pu resulting library file(s) in DIR
-# -arch ARCH override using `uname` to determine architecture
-# -archopt OPT specify an extra achitecture-specific option OPT
-# -noprefix don't prefix library name with "lib" nor add any suffix
-# -exports FILE only export the symbols listed in FILE
+# This script should be useful for projects other than Mesa.
+# Improvements/fixes are welcome.
+

-# 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 (unless the -noprefix option is used).
