# Time-guard script to run test program from other scripts (shell).
# 
#
# Usage:
#    check_exec_test.sh [-stdin] <cmd-line>
#
#    -stdin   - option used when application from <cmd-line> attempt
#               to read from std input (cgi applications for example).
#    cmd-line - command line to execute.
#
# Note:
#    The <cmd-line> should be presented with one application with
#    optional parameters only. Using scripts is not allowed here.
#
#    The CHECK_TIMEOUT environment variable defines a "timeout" seconds
#    to execute specified command line.By default timeout is 200 sec.
#
#    For protect infinity execution <cmd-line>, this script terminate 
#    check process if it still executing after "timeout" seconds.
#    Script return <cmd-line> exit code or value above 0 in case error
#    to parent shell.
