Hi,

Is there any command line parser which could handle long options preceded with single dash (e.g. "-help")?

There are at least two major packages for doing that, the gcc getopt
package and the popt package. Gcc getopt has two variants, long and
short. The short variant is the traditional getopt - options are
specified with an option string and are single letter. The long variant
permits long names; options are specified in a table. In both variants
the usage code has a loop and a switch statement.

The popt package supports long names; in it options are also specified
in a table. The interface is cleaner than the getopt interface.
Typically the usage code only needs to make a single call to the popt
package. It also has a bunch of nice options that you probably don't
need.
