Changes:
- Module documentation is sorted into a function description and a note
section is added where cmake_host_system_information() is mentioned as
an alternative.
- Module usage example is moved to a titled section at the end for
better readability.
- Instead of mentioning the physical processors count, the logical
processors is used as this is what is most likely wanted in most cases
and also all the used commands in this module return this number.
- Function's code style is synced a bit across the code base.
By default, kate will try to autodetect whether the project is
a svn or git checkout or not.
In case this does not give a satisfying result, the user can now
set CMAKE_KATE_FILES_MODE to the mode he wants.
Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool. Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience. Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.
Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices. It also references version control
history for more precise information. Therefore we no longer need to spell
out the list of Contributors in each source file notice.
Replace CMake per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online information
available from "https://cmake.org/licensing". The online URL also handles
cases of modules being copied out of our source into other projects, so we
can drop our notices about replacing links with full license text.
Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority
of the replacements mechanically. Manually fix up shebang lines and trailing
newlines in a few files. Manually update the notices in a few files that the
script does not handle.
