make — using OpenBSD make

SYNOPSIS

make [-f MAKEFILE]

: use bmake on linux. It's Slackbuild on Slackware.
: Slackware has a core package pmake which works as well (as far as I have tested).

DEFAULTS

makefile	: if no makefile is specified with -f makefile it defaults to makefile, Makefile.
target	: defaults to the first defined target, unless .MAIN: is specified.
echo	: it echoes the command unless the command is called @command.
errors	: exits on error unless ignored by calling -command.

MODIFIERS

:S	: Substitute string :S/old/new/
:C	: Substitute regex :C/pattern/replacement

USAGE

target:
	commands
target! #run even when up-to-date
target: prereq
target1 target2:
	@echo "this only displays this text but not the command itself."
	-cat /tmp/file_that_does_not_exist
VAR=something
VAR_RES!=command result
VAR_SUB=${VAR:S/STRING/REP/}
VAR_REGSUB=${VAR:C/REGEX/REP/}
target_show:
	echo 'target name: ' ${@}

EXAMPLE

t2:
	-cat Makefile
t1: t2
	cat makefile
makefile t3!
	echo ${@}
t4_t5:
	@echo 'target: ' ${@}
	@echo 'change t5 to t6: ' ${@:S/t5/t6/}
	@echo 't4: ' ${@:C/_.*$//}
	@echo 't5: ' ${@:C/^.*_//}

TODO
