GNU sharutils, version 4.2 This is the set of shar utilities. shar makes shell archives out of many files, preparing them for transmission by electronic mail services. 'unshar' helps unpacking shell archives after reception. uuencode prepares a file for transmission over an electronic channel while 'uudecode' does the converse transformation. RTR extensions to uudecode allow multiple files to be decoded from a single input stream. remsync allows for remote synchronization of directory trees, using electronic mail.
