The simple installation procedure includes copying files to their 
destination in /usr/local (that's the default) and processing the
encodings and fonts included with the package.

The default location for the config file is /etc/crops/crops.conf.
If you change that, either define the CROPS_CONFIG environment
variable, or specify --config option on the command line when invoking
crops tools.

To see install options, type:
perl install.pl -u

To install: 
perl install.pl [options]
