+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
