I am quite a newbie in TeX community. Previously, I had a TexLive installation from a DVD, and It did work pretty good. Now, I am on another machine with disk space constraint. So I chose to stay with the distro-based Texlive, I'm running fedora 22.
texlive.x86_64 4:2014-8.20140525_r34255.fc22 @System
What I really miss is tlmgr, I used it mainly to find package matching a specific word.
My question is How do you get help on Texlive? How do you know which packages match your need when you want to customize your document?
