Class
    Foam::argList
 
Description
    Extract command arguments and options from the supplied
    \a argc and \a argv parameters.
 
    Sequences with "(" ... ")" are transformed into a stringList.
    For example,
    \verbatim
        program -listFiles \‍( *.txt \‍)
    \endverbatim
    would create a stringList:
    \verbatim
        ( "file1.txt" "file2.txt" ... "fileN.txt" )
    \endverbatim
    The backslash-escaping is required to avoid interpretation by the shell.
 
    Default command-line options:
      - \par -case <dir>
        Select a case directory instead of the current working directory
      - \par -decomposeParDict <file>
        Read decomposePar dictionary from specified location
      - \par -parallel
        Specify case as a parallel job
      - \par -doc
        Display the documentation in browser
      - \par -srcDoc
        Display the source documentation in browser
      - \par -help
        Print the usage
 
    Additionally, the \b -noFunctionObjects and \b -postProcess options
    may be present for some solvers or utilities.
 
    Environment variables set by argList or by Time:
      - \par FOAM_API
        The value of foamVersion::api
      - \par FOAM_CASE
        The path of the global case.
        It is the same for serial and parallel jobs.
      - \par FOAM_CASENAME
        The name of the global case.
      - \par FOAM_EXECUTABLE
        If not already present in the calling environment,
        it is set to the \a name portion of the calling executable.
      - \par FOAM_APPLICATION
        If not already present in the calling environment,
        it is set to the value of the \c application entry
        (from \c controlDict) if that entry is present.
 
    The value of the \b FOAM_APPLICATION may be inconsistent if the value of
    the \c application entry is adjusted during runtime.
 
Note
    - The document browser used is defined by the \b FOAM_DOC_BROWSER
      environment variable or the <tt>Documentation/docBrowser</tt> entry
      in the <tt><etc>/controlDict</tt> file.
      The \%f token is used as a placeholder for the file name.
    - The valid (mandatory) arguments can be adjusted
      via the addArgument static method instead of directly
      manipulating the argList::validArgs static member.
    - The valid options can be adjusted
      via the addOption/removeOption static methods instead of directly
      manipulating the argList::validOptions static member.
