[tex-live] Adding programs to shell_escape_commands

[Br. Samuel Springuel]

So, now that gregorio will be in the shell_escape_commands list in 
TL2016 and beyond, I'm planning on modifying our installation 
instructions for TL2015 and earlier so that they instruct the user to 
add gregorio to the shell_escape_commands instead of using the 
--shell-escape option.  As part of that I'm considering writing a script 
which will do the leg work for those who are less comfortable with 
digging through their /usr directory (we have some Mac and Windows users 
that aren't comfortable with anything connected to the command-line). 
So far, I've got the basic steps for creating 
/usr/local/texlive/texmf-local/web2c/texmf.cnf (I'm starting with Mac 
and will translate for Windows later) and populating it with the 
existing shell_escape_commands as well as gregorio.

If /usr/local/texlive/texmf-local/web2c/texmf.cnf already exists then I 
don't want to just blindly over write it, but respect the current 
contents.  Now, so far, if all the file contains is the list of 
shell_escape_commands, then my script will respect that list and simply 
append gregorio to it.  My question is whether this is sufficient.  Can 
that file contain other information which I need to look for?




For reference, here is my script as I've written it thus far (obviously 
it needs to be run with sufficient privileges to write to 
/usr/local/texlive/texmf-local/web2c/texmf.cnf, usually root on a Mac):

mkdir -p /usr/local/texlive/texmf-local/web2c
temp=`kpsewhich --var-value=shell_escape_commands`"\\"
echo "shell_escape_commands = \\" > 
/usr/local/texlive/texmf-local/web2c/texmf.cnf
echo $temp >> /usr/local/texlive/texmf-local/web2c/texmf.cnf
echo "gregorio,\\" >> /usr/local/texlive/texmf-local/web2c/texmf.cnf
echo "" >> /usr/local/texlive/texmf-local/web2c/texmf.cnf
mktexlsr
