osrm-datastore needs usage info screen

[hoerup]

The other osrm-* programs has a nice usage info screen - but osrm-datastore lacks this

osrm-extract

[info] osrm-extract <input.osm/.osm.bz2/.osm.pbf> [options]:

Options:
-v [ --version ] Show version
-h [ --help ] Show this help message
-c [ --config ] arg (="extractor.ini")
Path to a configuration file.

Configuration:
-p [ --profile ] arg (="profile.lua") Path to LUA routing profile
-t [ --threads ] arg (=7) Number of threads to use

The datastore exposes visible options if you request help.
Those consist of generic and config options that are defined here.

but osrm-datastore lacks this

You then go on posting the extract help output --- is this by accident?

[hoerup]

my bad, -h works - but whereas the other executables also show the help screen if called without parameters, datastore just fails with an exception

and no - the output was no accident - it was just to show your other executables react on being called with out parameters.

[daniel-j-h]

Right, datastore should print the help in case no arguments are given and no ini file is available.
