You can set paths to various files here. The path is semicolon-separated list of directories,
each of them can contain environment variablesm, which will be automatically expanded,
such as $HOME
(which will
expand to user's home directory) or $LANG
(which can expand to name of selected locale)
There are also two special variables, $PDFEDIT_DATA
will expand to directory with
editor datafiles (/usr/local/share/pdfedit
by default) and $PDFEDIT_BIN
will expand to directory where the editor binary is located (/usr/local/bin
by default)
