Z:gnu-www-ja-questioning-sco--f55d3e-The Linux kernel is a computer/en

The Linux kernel is a computer program that combines copyrighted contributions from tens of thousands of individual programmers and firms. It is published and distributed under the GPL, which gives everyone everywhere permission to copy, modify and distribute the code, so long as all distribution of modified and unmodified copies occurs under the GPL and only the GPL. The GPL requires that everyone receiving executable binaries of GPL'd programs must get the full source code, or an offer for the full source code, and a copy of the license. The GPL specifies that everyone receiving a copy of a GPL'd program receives a license, on GPL terms, from every copyright holder whose work is included in any combined or derived work released under the license.
