UUENCODE is a C program which reads a file (often a binary file) and translates it to the UU encoding, by Stephen Satchell and Chuck Forsberg.
The resulting file is a text file.
The encoded file can often be transferred more easily than a binary file. The encoded file can be decoded by the UUDECODE, which recovers the original file, with its original name.
uuencode input > outputwill read the file input and write a UU encoded text version as the file output.
I2_BINARY_TO_ASCII a C++ program which converts a file of short int (I2) data from binary to ASCII format.
PIG_LATIN, a C program which translates a file to Pig Latin.
ROT13, a C++ program which reads a file of text and converts it to ROT13 text, and vice versa.
UUDECODE, a C program which translates a UU encoded file back to its original form.
