/* $RCSfile: dmake.c,v $
-- $Revision: 1.13 $
-- last change: $Author: kz $ $Date: 2008-03-05 18:28:04 $
--
-- SYNOPSIS
-- The main program.
--
-- DESCRIPTION
--
-- dmake [-#dbug_string] [ options ]
-- [ macro definitions ] [ target ... ]
--
-- This file contains the main command line parser for the
-- make utility. The valid flags recognized are as follows:
--
-- -f file - use file as the makefile
-- -C file - duplicate console output to file (MSDOS only)
-- -K file - .KEEP_STATE file
-- -#dbug_string - dump out debugging info, see below
-- -v[cdfimrtw] - verbose, print what we are doing, as we do it
-- -m[trae] - measure timing information
--
-- options: (can be catenated, ie -irn == -i -r -n)
--
-- -A - enable AUGMAKE special target mapping
-- -B - enable non-use of TABS to start recipe lines
-- -c - use non-standard comment scanning
-- -d - do not use directory cache
-- -i - ignore errors
-- -n - trace and print, do not execute commands
-- -t - touch, update dates without executing commands
-- -T - do not apply transitive closure on inference rules
-- -r - don't use internal rules
-- -s - do your work silently
-- -S - force Sequential make, overrides -P
-- -q - check if target is up to date. Does not
-- do anything. Returns 0 if up to date, -1
-- otherwise.
-- -p - print out a version of the makefile
-- -P# - set value of MAXPROCESS
-- -E - define environment strings as macros
-- -e - as -E but done after parsing makefile
-- -u - force unconditional update of target
-- -k - make all independent targets even if errors
-- -V - print out this make version number
-- -M - Microsoft make compatibility, (* disabled *)
-- -h - print out usage info
-- -x - export macro defs to environment
-- -X - ignore #! lines found in makefile
--
-- NOTE: - #ddbug_string is only availabe for versions of dmake that
-- have been compiled with -DDBUG switch on. Not the case for
-- distributed versions. Any such versions must be linked
-- together with a version of Fred Fish's debug code.
--
-- NOTE: - in order to compile the code the include file stddef.h
-- must be shipped with the bundled code.
