Re: [Tracker] Migrating tracker-utils/ into one 'tracker' command

Hi Martyn,

I like this idea a lot. Would it also be possible to make
tracker-$name in argv[0] to be recognized by the new 'tracker'
command's command line parsing to be the same as $name in argv[1]?

Then for one release we could just make symlinks from the old tool
names to the tracker binary, and keep the symlinks for one point
release (to maintain backward compatibility with scripts made with the
old tools' names in the bin directory).

That way we get the git commandline UI as proposed here, which I like
a lot, and we migrate cleanly to it.

So

tracker sparql -q "select ?a { ?a a nie:InformationElement }"

and

tracker-sparql -q "select ?a { ?a a nie:InformationElement }"

Are the same thing for at least one point release by letting
make-install do a ln -s /usr/bin/tracker /usr/bin/tracker-sparq and
adapt the argv command line to recognize it.

I guess something like (pseudo code)

copyarray(argv, n_argv)
if (s = split(n_argv[0], "-") != null) {
  movearray(n_argv, 1, argc, 2)
  n_argv[1]=s
}
parseargv(n_argv)

Kind regards,

Philip
