dnl Check a program for version sanity. The test runs a program, passes it an

dnl argument to make it print out some identification string, and filters that 
 |

dnl output with a regular expression. If the output is non-empty, the program
 | 
						|
dnl passes the sanity check.

						|
dnl   $1 - Name or full path of the program to run
 | 
						|
dnl   $2 - Argument to pass to print out identification string
 | 
						|
dnl   $3 - grep RE to match identification string
 |

dnl   $4 - set to 1 to make errors only a warning
