- * parse.c --
- *	Functions to parse a makefile.
- *
- *	One function, Parse_Init, must be called before any functions
- *	in this module are used. After that, the function Parse_File is the
- *	main entry point and controls most of the other functions in this
- *	module.
- *
- *	Most important structures are kept in Lsts. Directories for
- *	the .include "..." function are kept in the 'parseIncPath' Lst, while
- *	those for the .include <...> are kept in the 'sysIncPath' Lst. The
- *	targets currently being defined are kept in the 'targets' Lst.
- *
- *	The variables 'fname' and 'lineno' are used to track the name
- *	of the current file and the line number in that file so that error
- *	messages can be more meaningful.
- *
- * Interface:
- *	Parse_Init	    	    Initialization function which must be
- *	    	  	    	    called before anything else in this module
- *	    	  	    	    is used.
- *
- *	Parse_End		    Cleanup the module
- *
- *	Parse_File	    	    Function used to parse a makefile. It must
- *	    	  	    	    be given the name of the file, which should
- *	    	  	    	    already have been opened, and a function
- *	    	  	    	    to call to read a character from the file.
- *
- *	Parse_IsVar	    	    Returns TRUE if the given line is a
- *	    	  	    	    variable assignment. Used by MainParseArgs
- *	    	  	    	    to determine if an argument is a target
- *	    	  	    	    or a variable assignment. Used internally
- *	    	  	    	    for pretty much the same thing...
- *
- *	Parse_Error	    	    Function called when an error occurs in
- *	    	  	    	    parsing. Used by the variable and
- *	    	  	    	    conditional modules.
- *	Parse_MainName	    	    Returns a Lst of the main target to create.
