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 the same options as "0install run".

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
