Implemented input format validator

Overview

An Input format validator is a program that tests the input data for correctness.

A validator program must be an application (executable or interpreted) capable of being invoked with a command line call. The details of this invocation are described in Section 2 Invocation.

Invocation

The CCS will invoke the validator and passing it the input file on stdin.

The usage of the validator is as follows:

 ./validator < inputfile

Output

The input format validator may output debug information on stdout and stderr. This information may be displayed to the user upon invocation of the validator.

Exit codes

The input format validator must exit with code 42 on successful validation. Any other exit code is an error.
