# Parameter Operations
############################################

sub usage
{
	print <<Ende;
--------------------------------------------------------------------------------
make_download V1.0
The following parameter are needed:
-d: Full path to the file containing the follow-me info or to a directory
    containing the follow-me info files. In the latter case, all follow-me
    info files are evaluated. If a directory is used, the successfully used 
    follow-me info files are renamed using a string "success". Files with
    this string are ignored in repeated processes using "-d" with a 
    directory.

The following parameter are optional:
-nodownload: Only signing, no creation of download sets (Windows only)
-useminor: Important for installation sets, created without minor set
-writetotemp: Necessary, if you do not want to write into solver
              This can be caused by missing privileges (Windows only)
-internalcabinet: Not only the cabinet files are signed, but also all
                  files included in the cabinet files (Windows only).

-sign: Uses signing mechanism to sign installation sets
If \"-sign\" is set, the following two parameter are required:
-pfx: Full path to the pfx file
-pw: Full path to the file, containing the pfx password.

Examples:

Specifying an installation set (with "-d"):

perl make_download.pl -d <followmeinfofilename>

perl make_download.pl -d <followmeinfofilename>
                         -sign
                         -pfx <pfxfilename>
                         -pw <passwordfilename> 
                               
or without specifying an installation set:

perl make_download.pl -d <followmedirectory>
                      -sign
                      -pfx <pfxfilename>
                      -pw <passwordfilename>
