+NAME
+ preprocessor
+
+DESCRIPTION
+ The LPC driver understands the following preprocessor
+ directives:
+
+ #include, #define, #if, #ifdef, #ifndef, #else, #elif,
+ #endif, #undef
+ same as in ANSI C
+
+ #line <num>
+ line numbers start at <num> with the next line
+
+ #echo
+ the rest of the line is printed to the error output
+ (stderr), thus can be captured into a log file
+
+ #pragma
+ see the separate man page
