NAME

       Source-highlight-settings - utility that can be used to write a configuration file for GNU Source-highlight (and its library)

SYNOPSIS

       source-highlight-settings

DESCRIPTION

       Since  version  3.0,  GNU  Source-highlight  includes  also  the  utility  source-highlight-settings,  which  can  be used to check whether
       source-highlight will be able to find its language definition files, and other configuration files, and in case, to store the correct  set-
       tings in a configuration file, in the user home directory.

       In particular, the stored configuration file will be called source-highlight.conf and will be stored in $HOME/.source-highlight/.

       For the moment, this file only stores the default value for the --data-dir option.

       This utility is part of GNU Source-highlight, maintained by:
