 # 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).
