Usage: tllocalmgr  
       tllocalmgr [options] [command] [args]

       Running tllocalmgr alone starts the TeXLive local manager shell 
       for Arch Linux. This shell is capable of command-line completion!
       There you can look at the available updates with the command 'status' 
       and you can install individual CTAN packages using 'install' or 'update'
       under \$TEXMFLOCAL. This is done by creating a package texlive-local-<pkg>
       and installing it with pacman. Note that this won’t interfere with your 
       standard texlive installation, but files under \$TEXMFLOCAL will take
       precedence.  
       
       Here are the commands available in the shell:

Commands:       
              status   --   Current status of TeXLive installation
           shortinfo * --   Print a one-liner description of CTAN packages
                info * --   Print info on CTAN packages
              update * --   Locally update CTAN packages
             install * --   Locally install new CTAN packages
          installdoc * --   Locally install documentation of CTAN packages
          installsrc * --   Locally install sources of CTAN packages
           listfiles * --   List all files in CTAN packages
              search * --   Search info on CTAN packages
         searchfiles * --   Search for files in CTAN packages
             texhash   --   Refresh the TeX file database
               clean   --   Clean local build tree
                help   --   Print helpful information
                quit   --   Quit tllocalmgr

        The commands followed by * take one of more package names as arguments.
        Note that these can be completed automatically by pressing TAB.

        You can also run tllocalmgr as a standard command-line program, with
        one of the above commands as argument, then the corresponding task will
        be performed and the program will exit (except when the command is 'status').

        tllocalmgr accepts the following options:
