texlive - remove context mkiv.

Browse Source 
Explain why context is not present.

In the the unlikely event that somebody wishes to build context
from source, link to my old comments in the 2023 ticket, and to
the source tags at github.

Also mention that first installing (only) context from the binary
sounds like the easiest way to do this - the way we used to use the
full binary to bootstrap the source build.

Change a lingering 'command' to 'parameter' in the explanations.

<para>
TeXLive includes some files for ConTeXt but the source of that is
separate and has moved on from using luatex in the previous 'mkiv'
version to using luametatex which can be pulled with git from <ulink
url="https://github.com/contextgarden/luametatex/tags">github luametatex</ulink>.
LuaMetaTeX uses meson and ninja, but it does not fit easily into
the BLFS layout of TeXLive.
<!-- FIXME - when removing, keep that link to luametatex tags, and note
that building and installing that to fit with a BLFS install of TeXLive
will not be a trivial exercise.-->
</para>
<para>
However, with a little extra work 'mkiv' files can still be processed
using the files shipped in texmf.
TeXLive does not include the source for ConTeXt, only the items that
are at CTAN. Trying to build ConTeXt purely from source on a BLFS
TeXLive system is a niche usage and looks as if it will be more trouble
than it is worth.
</para>
<para>
<emphasis>Fixes to use ConTeXt will be removed when the texlive source next
has to be updated for either a vulnerability fix which requires backporting
luatex changes, or for TeXLive 2024. If you are a BLFS user of ConTeXt you
should be prepared to use the latest tag from github (the link is
in first paragraph of this Note). Building and installing that to work with
a BLFS install of TeXLive will not be a trivial exercise.</emphasis>
If you wish to use ConTeXt with <command>luametatex</command> (most of
the old MKII and MKIV code was removed from TeXLive 2023 by the ConTeXt
developer), starting with the binary (only installing ConTeXt) would
probably be the easiest way to bootstrep it. The source for
<command>luametatex</command> can be pulled with git from <ulink
url="https://github.com/contextgarden/luametatex/tags">github
luametatex</ulink>, compiled with meson and ninja, and installed by
copying to the correct program directory. This should avoid having to
fix all the symlinks etc and also avoid including the many unrelated
<!-- trying to use a filename tag here is rejected within para ?? -->
parts of texmf-dist.
