> Is $RM defined anywhere now? Or $LN? Or $MKDIR? They still seem to be
used by the gap spkg, so I can't figure out why that package installs
correctly with this version of sage-env.
I'm not sure if Or $RM, $LN or $MKDIR are defined elsewhere, or if the
bits in gap don't work, but it is not apparent they are not working. But
there does seem to be no point in having variables for such basic
commands, as agreed here.

I left 'cp', as potentially the GNU version of CP has some extra options
over some other implementations of CP which might make it useful in some
cases, though I'd much prefer any GNUisms were avoided. But there really
is no point in having variable for 'ln' or 'mkdir'
They are all part of POSIX, the 2008 edition of which can be found here

I'm not a great fan of GNU standards and I don't agree with some of it
here, but even they agree one can rely on rm, ln and mkdir.

I've created a ticket for their removal from 'gap' - see #7873 . I'll fix
that very shortly.
