This adds a warning to the top of each “boot” package that reads: Note: this package is used for bootstrapping fetchurl, and thus cannot use fetchpatch! All mutable patches (generated by GitHub or cgit) that are needed here should be included directly in Nixpkgs as files. This makes it clear to maintainer that they may need to treat this package a little differently than others. Importantly, we can’t use fetchpatch here due to using <nix/fetchurl.nix>. To avoid having stale hashes, we need to include patches that are subject to changing overtime (for instance, gitweb’s patches contain a version number at the bottom).

''gzip (GNU zip) is a popular data compression program written by
|
|
Jean-loup Gailly for the GNU project. Mark Adler wrote the
|
|
decompression part.
|
|
|
|
We developed this program as a replacement for compress because of
|
|
the Unisys and IBM patents covering the LZW algorithm used by
|
|
compress. These patents made it impossible for us to use compress,
|
|
and we needed a replacement. The superior compression ratio of gzip
|
|
is just a bonus.
