A package is a file or collection of files containing extra La Te X commands and programming which add new styling features or modify those already existing.
In practice there is no problem in having even a couple of dozen packages active. The main place to look for style packages on the Internet is CTAN.On windows we use Miktex and just update to all the latest packages. Should we move questions about fetching updates from CPAN to Super User too? Search on "[perl] CPAN update" suggested that CPAN management is in, so I think that CTAN management should be too.Is there a way to update the packages in texlive to the latest from CTAN without going through the laborious process? I freely admit that this is not an immediate help, but given enough votes for the "Ubuntu idea" it might help in future releases - so I felt justified in posting it here.For instance, the free GNU/Linux distributions, and the distributions from Red Hat, Debian, Ubuntu, SUSE, etc., all make Te X installations derived from Te X Live available through their normal packaging system (, etc.).If this is how you got your Te X, the timing and content of updates is entirely up to your operating system provider—contact them with any and all questions.Here, the first thing to try, both to install new packages and to update already installed ones, is to run (on a command line/system prompt) the command .If that doesn't get the material that you want, then here is one possibility.At the moment I have Tex Live 2014 installed from slackbuilds.You may have gotten Te X Live in one of two fundamentally different ways.I am using texlive on ubuntu and having issues with some packages used as they are too old.Downloading them from CTAN manually and installing fixes them but this is time consuming.
