For example: I have a directory bin/ in my home directory, that also
is in my PATH. Once upon a time, I did
sage: install_scripts('~/bin/')
In principle, you could name any directory to which you have write
permission. In that directory, Sage creates a couple of scripts: gap
gp hg ipython maxima mwrank R singular
There is not much magic in the scripts. For example, the "gap" script
is
#!/bin/sh
sage -gap $*
Hence, if I do
gap
in a shell, then in fact "sage -gap" is executed; so, it uses the gap
shipped by Sage, but it doesn't start Sage.
Apparently the scripts don't need to change if the Sage-gap, -
singular, -gp,... versions change. Hence, when I say "once upon a
time", it was really only *once*.
Remark: You ask if it is possible to make "python or R" available. I
don't know if it is possible to ask the install_scripts function to
*only* install python and R but nothing else. Also I notice that there
is no script called "python" in the list above; but it would of course
be easy to write such script.

Sorry, that post is beyond my knowledge. I even don't know if it is
related.
