+Multiple \fI-I\fR options can be supplied to add additional directories.

+Specifies the output directory for PPD files.
+The default output directory is "ppd".
+.TP 5

+The default language is "en" (English).
+Separate multiple languages with commas, for example "de_DE,en_UK,es_ES,es_MX,es_US,fr_CA,fr_FR,it_IT" will create PPD files with German, UK English, Spanish (Spain, Mexico, and US), French (France and Canada), and Italian languages in each file.
+.TP 5
+.B \-m
+Specifies that the output filename should be based on the ModelName value instead of FileName or PCFilenName.
+.TP 5

+.TP 5
+.B \-v
+Specifies verbose output, basically a running status of which files are being loaded or written.
+.B \-z

+The default is to generate uncompressed PPD files.

+.TP 5
+\fB\-\-crlf\fR
