2 # The perl script requires the following variables to be bound
3 # to something meaningful before it will operate correctly:
10 # * a program to run (1st arg)
11 # * some "command-line opts" ( -O<opt1> -O<opt2> ... )
12 # [default: anything on the cmd line this script doesn't recognise ]
13 # the first opt not starting w/ "-" is taken to be an input
14 # file and (if it exists) is grepped for "what's going on here"
16 # * a file to feed to stdin ( -i<file> ) [default: /dev/null ]
17 # * a "time" command to use (-t <cmd>).
19 # * alternatively, a "-script <script>" argument says: run the
20 # named Bourne-shell script to do the test. It's passed the
21 # pgm-to-run as the one-and-only arg.
23 # Run the program with those options and that input, and check:
26 # * an expected exit status ( -x <val> ) [ default 0 ]
27 # * expected output on stdout ( -o1 <file> ) [ default /dev/null ]
28 # ( we'll accept one of several...)
29 # * expected output on stderr ( -o2 <file> ) [ default /dev/null ]
30 # ( we'll accept one of several...)
32 # (if the expected-output files' names end in .Z, then
33 # they are uncompressed before doing the comparison)
35 # (This is supposed to be a "prettier" replacement for runstdtest.)
39 # -accept-output replace output files with the ones actually generated by running
