Options for the install4j command line compiler

The install4j command line compiler has the following options:

-h or --help
Displays a quick help for all available options.
-V or --version
Displays the version of install4j in the following format:
```
    install4j version 2.0, built on 2003-10-15
        
```
-v or --verbose
Enables verbose mode. In verbose mode, install4j prints out information about internal processes. If you experience problems with install4j, please make sure to include the verbose terminal output with your bug report.
-q or --quiet
Enables quiet mode. In quiet mode, no terminal output short of a fatal error will be printed.
-t or --test
Enables test mode. In test mode, no media files will be generated in the media file directory.
-L or --license=KEY
Update the license key on the command line. This is useful if you have installed install4j on a headless system and cannot start the GUI. KEY must be replaced with your license key.
-r STRING or --release=STRING
Override the application version defined in the general settings step. STRING must be replaced with the desired version number. The version number may only contain numbers and dots.
-d STRING or --destination=STRING
Override the output directory for the generated media files. STRING must be replaced with the desired directory. If the directory contains spaces, you must enclose STRING in quotation marks.
-s or --build-selected
Only build the media files which have been selected in the install4j GUI. By default, all media files are built regardless of the selection in the build step.
-b LIST or --build-ids=LIST
Only build the media files with the specified IDs. LIST must be replaced with a comma separated list of numeric IDs. The IDs for media files can be shown in the install4j GUI by choosing Media->Show media file IDs from the main menu when the media file step is visible. Examples would be:
```
    -b 2,5,9
    --build-ids=2,5,9
        
```
-m or --media-types=T[,T]
Only build media files of the specified type. T must be replaced with a media file type recognized by install4j. To see the list of supported media types, execute install4jc --list-media-types. Examples would be:
```
    -m win32,macos,macosFolder
    --media-types=win32,macos,macosFolder
        
```
-D NAME=VALUE[,NAME=VALUE]
Override a user variable with a different value. You can override multiple variables by specifying a comma separated list of name value pairs. NAME must be the name of a variable that has been defined on the user variables tab of the general settings step. The value can be empty.
To override a variable for a specific media file definition only, you can prefix NAME with ID: to specify the ID of the media file. The IDs for media files can be shown in the install4j GUI by choosing Media->Show media file IDs from the main menu when the media file step is visible.
Examples would be:
```
    -D MYVARIABLE=15,OTHERVARIABLE=
    "-D MYVARIABLE=15,OTHERVARIABLE=test,8:MEDIASETTITLE=my title"
        
```
-f or --var-file
Load variable definitions from a file. This option can be used together with the -D option, which takes precedence if a variable occurs twice. The file can contain
- variable definitions
  One variable defnition per line of the form NAME=VALUE.
- blank lines
  blank lines will be ignored.
- comments
  lines that start with # will be ignored.
The file is assumed to be encoded in the UTF-8 format. Should you require a different encoding you can prefix the filename with CHARSET:, where CHARSET is replaced with the name of the encoding.
Examples would be:
```
    -f varfile.txt
    --var-file=ISO-8859-3:varfile.txt
        
```
-M or --list-media-types
Prints out a lists of supported media types for the --media-types option and quits.
