- /**
- * Builds the StaticGLInfo class from the OpenGL header files (i.e., gl.h
- * and glext.h) whose paths were passed as arguments to {@link
- * #main(String[])}.
- *
- * It relies upon the assumption that a function's membership is scoped by
- * preprocessor blocks in the header files that match the following pattern:
- * <br>
- *
- * <pre>
- *
- * #ifndef GL_XXXX
- * GLAPI <returnType> <APIENTRY|GLAPIENTRY> glFuncName(<params>)
- * #endif GL_XXXX
- *
- * </pre>
- *
- * For example, if it parses the following data:
- *
- * <pre>
- *
- * #ifndef GL_VERSION_1_3
- * GLAPI void APIENTRY glActiveTexture (GLenum);
- * GLAPI void APIENTRY glMultiTexCoord1dv (GLenum, const GLdouble *);
- * GLAPI void <APIENTRY|GLAPIENTRY> glFuncName(<params>)
- * #endif GL_VERSION_1_3
- *
- * #ifndef GL_ARB_texture_compression
- * GLAPI void APIENTRY glCompressedTexImage3DARB (GLenum, GLint, GLenum, GLsizei, GLsizei, GLsizei, GLint, GLsizei, const GLvoid *);
- * GLAPI void APIENTRY glCompressedTexImage2DARB (GLenum, GLint, GLenum, GLsizei, GLsizei, GLint, GLsizei, const GLvoid *);
- * #endif
- *
- * </pre>
- *
- * It will associate
- * <code> glActiveTexture </code> and
- * <code> glMultiTexCoord1dv </code>
- * with the symbol
- * <code> GL_VERSION_1_3 </code>,
- * and associate
- * <code> glCompressedTexImage2DARB </code> and
- * <code> glCompressedTexImage3DARB </code>
- * with the symbol
- * <code> GL_ARB_texture_compression </code>.
