HELP="Check your programs with Input files
Usage: check.sh [-hc] [-p PROG]	[-g/r/n color]
check.sh detects the executable (last modified) automatically,
as well as the Testdata

Supported Input-Files:
 * *.in
 * grader.in.* (RunC)
 * [name].in.* (COCI)
Supported Output-Files:
 * *.out
 * *.sol
 * *.ans
 * grader.expect.* (RunC)
 * [name].out.* (COCI)

PARAMETERS:
 * To turn off colors use the optional Parameter -c
 * To show this help message give me a -h
 * and to manually define the program use -p PROGNAME
   use a format like this: \"-p ./prog\"
 * You can also define your own colors with
	\t-r for the red color
	\t-g for green and
	\t-n for default / normal color
