This is a data file of coastlines, countries, rivers, islands and lakes of the world compiled by the CIA and now de-classified into the public domain. This file is broken up into 5 pieces, so you have to get them all separately and 'cat' them together. The file is tightly packed in a binary format, and to read it you will need to use the C program contained in the archive, 'domap.c'. However it seems to be the best source for free world map data. The source includes both 'print to screen' and 'print to printer' versions.
Executable versions are here too.
