This commit:
1. Updates the COPYRIGHT file with all the contributors to ksh
93u+m since the reboot, based on the commit history, sorted by
number of commits in descending order. It also separates the
authors of backported contributions from direct contributors.
2. Adds missing contributors of source each file to that file's
copyright header based on that file's commit history.
The script used to maintain this is now up at:
https://github.com/ksh93/ksh/wiki/update-copyright.sh
In addition, the original ast copyright notice is restored to
its EPL 1.0 version -- that is what AT&T Intellectual Property
originally licensed this code under, and we are the ones who
upgraded it to EPL 2.0 (as allowed by EPL 1.0) in 441dcc04.
The history should be accurate.

[+NAME?mamprobe - generate MAM cc probe info]
|
|
[+DESCRIPTION?\bmamprobe\b generates MAM (make abstract machine) \bcc\b(1)
|
|
probe information for use by \bmamake\b(1). \acc-path\a is the
|
|
absolute path of the probed compiler and \ainfo-file\a is where
|
|
the information is placed. \ainfo-file\a is usually
|
|
\b$INSTALLROOT/lib/probe/C/mam/\b\ahash\a, where \ahash\a is a hash
|
|
of \acc-path\a. Any \ainfo-file\a directories are created if needed.
|
|
If \ainfo-file\a is \b-\b then the probe information is written to
|
|
the standard output.]
|
|
[+?\bmamprobe\b and \bmamake\b are used in the bootstrap phase of
|
|
\bpackage\b(1) installation before \bnmake\b(1) is built. The
|
|
probed variable names are the \bnmake\b(1) names with a \bmam_\b
|
|
prefix, \bCC\b converted to \bcc\b, and \b.\b converted to \b_\b.
|
|
Additional variables are:]{
|
|
[+_hosttype_?the \bpackage\b(1) host type]
|
|
[+mam_cc_L?\b-L\b\adir\a supported]
|
|
