NAME

       0launch — download and run programs by URL

SYNOPSIS

       0launch [OPTION]... PROGRAM [ARG]...

DESCRIPTION

       0launch   runs   the   given   program.   PROGRAM   is   either   a   URL   in   the  form
       `http://site/program.xml' or a local path name like `/path/to/program.xml'.

       If the program is not already on your computer, 0launch downloads information about  which
       versions  are available, and lets you choose one to download. It will also (automatically)
       do the same for any libraries the program needs.

       Note that much of the functionality that was  originally  in  0launch  has  now  moved  to
       0install(1).

       0launch PROGRAM ARGS

       is roughly equivalent to

       0install run PROGRAM ARGS

       See the 0install(1) man-page for more information.

EXAMPLES

       When  a  program  is  available  using 0launch, it will have an associated URL. To run the
       program, simply invoke 0launch with this as an argument:

       0launch http://rox.sourceforge.net/2005/interfaces/Edit

       The first time you do this, details about the program are downloaded and cached,  and  you
       will  be prompted to confirm the versions to use. In future, the program will run directly
       from the cache without confirmation.

       To check for new versions:

       0launch --refresh http://rox.sourceforge.net/2005/interfaces/Edit

       To avoid having to keep typing the full URI, use the  `0install  add'  command  to  create
       shortcuts to run your programs.

COMMAND-LINE OPTIONS

       0launch  takes  many  of  the  same  options  as  "0install run". This page just lists the
       differences:

       -d, --download-only
              Deprecated. Use "0install download" instead.

       -f, --feed
              Deprecated. Use "0install add-feed" or "0install remove-feed" instead.

       --get-selections
              Deprecated. Use "0install select" instead.

       -i, --import
              Deprecated. Use "0install import" instead.

       -l, --list
              Deprecated. Use "0install list" instead.

       --select-only
              Deprecated. Use "0install select" instead.

       --set-selections=FILE
              Deprecated. Just give FILE as the PROGRAM.

       --show Deprecated. Use "0install select" instead.

DEBUGGING TIPS

       To debug 0launch itself, use the --verbose and --console options. For example:

       $ 0launch -vvc http://myprog

       To trace or debug programs run by 0launch, use the --wrapper option.  For example, to  run
       myprog --help, displaying all calls to open(2):

       $ 0launch --wrapper="strace -e open" http://myprog --help

       If  your  program  is  interpreted  (e.g.  a  Python  program),  and you wish to debug the
       interpreter running it, you can do it like this:

       $ 0launch --wrapper="gdb --args python" http://myprog --help
