needs of the GLSL language. The requirements for this preprocessor are
specified in the GLSL 1.30 specification availble from:

This specification is not precise on some semantics, (for example,
#define and #if), defining these merely "as is standard for C++
-preprocessors". To fill in these details, I've been using the C99
-standard (for which I had a convenient copy) as available from:

-Known limitations
------------------
-Macro invocations cannot include embedded newlines.
+Any downstream compiler accepting output from glcpp should be prepared
+to encounter and deal with the following preprocessor macros:
-The __LINE__, __FILE__, and __VERSION__ macros are not yet supported.
+ #line
+ #pragma
+ #extension
-The argument of the 'defined' operator cannot yet include enclosing
-parentheses.
+All other macros will be handles according to the GLSL specification
+and will not appear in the output.
-The #error, #pragma, #extension, #version, and #line macros are not
-yet supported.

A file that ends with a function-like macro name as the last
non-whitespace token will result in a parse error, (where it should be
