| ! This program converts .gpl files in the Scientific Colour Map directory and its subdirectories to .lut files. | ||
| ! The .lut files are written to the same directory, and copies are made to the current directory. | ||
| ! It also prints the list of all .lut files. | ||
| ! Note: This program is intended for use on Linux/Unix systems. | ||
