Routine Description:

    Parse and syntactically validate arguments specified on the comment line.

    The following arguments are valid:

    /a                  forces the external progress indicator on the setup page

    /c                  disallow cancel during final installation phase

    /i:<master_oc_inf>  specifies the master OC inf (required).

    /n                  forces specified master_oc_inf to be treated as new.

    /s:<master_oc_inf>  specifies the source path (required).

    /u:<unattend_spec>  specifies unattended operation parameters.

    /x                  supresses the 'initializing' banner

    /q                  run wizard invisibly

    /r                  supress reboot if need on unattended operation

    /w                  warn on reboot on unattended operation

Arguments:

    Standard main argc/argv.

Return Value:

    Boolean value indicating whether the arguments specified are valid.

    If successful, various global variables will have been filled in.
    If not, the user will have been informed.
