I'm on Windows behind a firewall (you're offering your sympathies; I know; thanks). I need to add the package
xcolor to MiKTeX.
xcolor.zip and unpack it in
c:/Users/<username>/AppData/Local/Programs/MiKTeX 2.9/tex/latex alongside the packages that came with MiKTeX.
Does there exist an "add to the index" MiKTeX command that does not need network access?
miktexsetup make it possible to set up a local repository other than through
--package-set=complete download? Using this pair requires network access.
