+
+# 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
+#
+
+
+#
+# Option defaults
