--style optionThe ‘--style=style_file’ option specifies the style file to use
when colorizing. It has an effect only when the --color option is
effective.
If the --style option is not specified, the environment variable
PO_STYLE is considered. It is meant to point to the user's
preferred style for PO files.
The default style file is $prefix/share/gettext/styles/po-default.css,
where $prefix is the installation location.
A few style files are predefined:
You can use these styles without specifying a directory. They are actually
located in $prefix/share/gettext/styles/, where $prefix is the
installation location.
You can also design your own styles. This is described in the next section.
