I am looking for EL & RPMs of specific LaTeX utilities compatible with 
the TeX/LaTeX base/packages installed from the SL7 install DVD:

XeLaTeX

Biber

Texindy

Makeglossaries

Asymptote

I have found these as installable images for other distros, including 
some Fedora.  If these packages are available by some other mechanism 
such that the SL7 Latex system can download, compile, insert, etc., any 
of these, advice and instructions would be most appreciated.

As a fast LaTeX GUI front end, I use Texstudio that has a X86-64 CentOS 
7 RPM available at the Texstudio Sourceforge site and that installs and 
runs fine under SL 7.  The only WYSIWYG I have found is BaKoMaTeX that 
is licensed for fee (with actual pricing in Euros).  Is there any 
licensed-for-free LaTeX WYSIWYG (not LyX that produces LaTeX but 
internally is not LaTeX)?  Thus far, I have not found such a WYSIWYG.
