Gummi is a LaTeX editor for the Linux platform, written in Python and GTK. It was designed with simplicity in mind, but hopes to attract both novice and more advanced users.
It has received good reviews and is growing into an excellent tool for Latex users.
If you are using Fedora 11. Good news indeed. you can download the rpm to install. However, there is a lot of dependency from GTK and Python, you may want to use "yum localinstall" to resolve dependences
After downloading the rpm,
# yum localinstall gummi-0.4.2-1.noarch.rpm
