Comment(by glynn):

 Replying to [comment:15 annakrat]:

 > The 'which' implementation of function find_program more suits to the
 name. But in this case we probably want to only test if we can run it (and
 we don't want to find it).

 Indeed.

 > Is there a way to get rid of the dummy parameters (like 'help') and keep
 the interface clean while keeping the previous implementation?

 Some of the programs which are tested for need a parameter like "help" to
 make them return immediately rather than e.g. starting up a GUI. But if we
 ignore the exit code, we can probably remove the parameter from many of
 them (without e.g. a --help switch, many programs will complain about
 missing parameters and return a non-zero exit code).
