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
