Less is a program similar to more (1), but which allows backward movement in the file as well as forward movement. Also, less does not have to read the entire input file before starting, so with large input files it starts up faster than text editors like vi (1). This enhanced less support ISO 2022 code extension techniqes and Japanese codes(EUC Japanese, SJIS) and compressed(or gzipped) file viewing. The author of this patch is jam@pobox.com.
