DESCRIPTION:The include file for reading TimberWolf parameter files.
CONTENTS:   
DATE:	    Oct 25, 1990 
REVISIONS:  Sat Jan 26 12:36:04 PST 1991 - added genrows GENR to 
		list of programs.
	    Sat Feb 23 00:46:29 EST 1991 - added TOMUS program and
		added wildcarding argument to Yreadpar_next.
	    Thu Apr 18 00:53:01 EDT 1991 - added design rule
		parameter extraction routines.

Function:
    Initializes the readpar mechanism.  This must be call before any
    other readpar functions.  Restrictions: only one parameter file
    may be read at a time.  Design_name is the name of the design. 
    Program is one of the listed program id's at the top of this 
    file.  The filter is used to screen out other programs. There
    are two ways of initializing the parameter files.  In the
    first case program = USER, and filter is one of the programs
    such as SGGR.  The second way is to specify program =
    filter = program such as SGGR.  If abort flag is set true, the
    routine will exit program if file is not found.  If abort flag is
    set false, it will ignore any subsequent readpar commands 
    relating to this file.

Function:
    Reads a parameter one line at a time ignoring comments. Returns
    only parameters which pertain to the given program.  Nothing
    is stored in memory.  Lineptr is the contents of the current
    line, line is the current line number. Numtokens is the 
    number of tokens returned and onNotOff tells the state of
    the variable.   Wildcard returns whether this line is
    a wildcard.  Wildcard should not generate error messages 
    in the programs readpar file.
