I used to use LaTeX in Windows and there was Miktex Package Manager with which it was very easy to add a missing package. I wanted to install
textcomp to Ubuntu 11.10 and it requires me to download the zip from here and find the packages which are in
/usr/share/texmf-texlive/tex/latex in my case, extract the zip contents to there, and update the packages.
Is there a package manager which does installation and removal in an easier way like the Miktex Package Manager in Windows?
