ISTR that when I first touched the texlive installer, I changed its
page to say : The programs are always installed in an <ARCH>-linux
subdirectory.

 Fernando later noticed that on i686 the directory is called
i386-linux, so the next sentence now says: Always replace <ARCH> by
x86_64, for 64bit, or by i386, for 32bit, respectively, depending on
the architecture that you are using in your actual installation
location.

 For people who read the book that is probably adequate, but I guess
that it breaks copy-and-paste scripts, and scripts which work from
the XML (e.g. jhalfs).  Would it help if I changed it to:

 "The programs are always installed in an <ARCH>-linux subdirectory,
and on 32-bit x86 this is always i386-linux. For x86_64 and i?86 we
can generate this as $TEXARCH:

export TEXARCH=$(uname -m | sed -e 's/i.86/i386/' -e 's/$/-linux/')

cat >> extrapaths.sh as now, except
(i.) cat ... << EOF
 i.e. NOT "EOF" because we want it to evaluate the variable
(ii.) last line:
pathappend /opt/texlive/2014/bin/$TEXARCH

unset TEXARCH"

Yes ? No ?
