[PATCH v2 2/2] commands/*: Replace license and copyright boilerplate by SPDX identfiers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



While at it also drop references to the non-existing CREDITS file and do
some small rearrangements for some uniform formatting.
(SPDX-License-Identifier first, then copyright texts and then an empty
line.)

The advantage is that these specifiers are machine-parseable which helps
license conformance.
