 PURPOSE
-    Description of the invocation of the gamedriver, especially of the command

-    the related documentation.

 DESCRIPTION
-    The driver is invoked from the commandline as other normal programs.
-    Neither the current directory nor the directory the executable is in need
-    to be in any special relation the directory of the mudlib. Once the driver
-    is running, it emits two streams of outputs:

+        the driver is running, it emits two streams of outputs:
 
-      - driver-related messages on stderr; this unfortunately includes
-        LPC compiler diagnostics
-      - LPC runtime-related messages in the logfile <mudlib>/<host>.parse.log

-DESCRIPTION -- Argument Parser
-    The parser analyses the commandline arguments given with the driver
-    invocation and distinguishes 'options', which start with a '-', from
-    proper arguments. Options are further distinguished by their name and
-    may take an additional value. In general, options and arguments can be
-    givein in any order.

-    Options are recognized in two forms. In the short form the option must
-    be given as a single '-' followed by a single letter. In the long form,
-    options start with '--' followed by a string of arbitrary length. The
-    short options are case sensitive, the long options aren't.
-    Most options can be specified in both the short and long form, but that
-    is not mandatory. Examples: '-r' and '--recursive'.

-    If an option takes a value, it must follow the option immediately after
-    a separating space or '='. Additionally, the value for a short option
-    may follow the option without separator. Examples are: '-fMakefile',
-    '-f Makefile', '--file=Makefile' and '--file Makefile'.

+        '-f Makefile', '--file=Makefile' and '--file Makefile'.
 
-    Short options may be collated into one argument, e.g. '-rtl', but
-    of these only the last may take a value.

+        arguments are considered proper arguments even if they start with a '-'
+        or '--'.
 
-    The arguments are usually taken from the commandline; but the parser
-    is also able to read them from a textfiles, which can be nested. The
-    content of the textfiles is broken down into words delimited by whitespace,
-    which are then treated as given on the commandline at the place where
-    the instruction to read the textfile stood.

-    The file parser recognizes simple double-quoted strings, which must be
-    contained on a single line. Additionally, the '#' character given by
-    itself is a comment marker - everthing after the '#' until the end
-    of the current line is ignored.
