These scripts have been contributed by the developers and users of Bioperl. The scripts in scripts/ are production quality scripts that have POD documentation and accept command-line arguments, and all of these scripts have the PLS suffix. You can install the scripts in the scripts/ directory if you'd like, simply follow the instructions on 'make install'. The installation directory is specified by the INSTALLSCRIPT variable in the Makefile, the default directory is /usr/bin. Installation will copy the scripts to the specified directory, change the 'PLS' suffix to 'pl' and prepend 'bp_' to the script name if it isn't so named already. Please contact bioperl-l at bioperl.org if you are interested in contributing your own script.
