Update NEWS docs. Enhance the manual to use automake version.texi, and use the canonical FSF copyright features and statement. Some $(realpath ...) tests won't work on Windows; leave them out The jobserver filedescriptor test might fail if some FDs are reserved, so for now comment out that check.

rules. The first rule has a series of sleep and echo commands

echo statement. When make is called in this test, it is given

the -j option with a value of 4. This tells make that it may

start up to four jobs simultaneously. In this case, since the

first command is a sleep command, the output of the second
