18 0launch runs a program, identified by an `INTERFACE'. If the program is not
19 already on your computer, it downloads information about which versions are
20 available, and lets you choose one to download. It will also (automatically)
21 do the same for libraries the program needs.
24 0launch will also check for updates if it has been a long time since the last
26 0launch therefore allows users to download and upgrade software without
30 An INTERFACE can be either a URL in the form `http://site/program' or
31 a local path name like `/path/to/program.xml'. For HTTP URLs, the remote
32 file is a GPG-signed XML document. Local interface files are not signed.
37 When a program is available using 0launch, it will have an associated URL. To
38 run the program, simply invoke 0launch with this as an argument:
40 .B 0launch http://rox.sourceforge.net/2005/interfaces/Edit
43 The first time you do this, details about the program are downloaded and
44 cached, and you will be prompted to confirm the versions to use. In future,
45 the program will run directly from the cache without confirmation.
48 To check for new versions:
50 .B 0launch --refresh http://rox.sourceforge.net/2005/interfaces/Edit
53 To search the list of cached URLs:
55 .B 0launch --list Edit
58 To avoid having to keep typing the full URI, use the 0alias(1) command
59 to create shortcuts to run your programs.
61 .SH COMMAND-LINE OPTIONS
64 \fB-c\fP, \fB--console\fP
65 Never use the GUI. Normally, 0launch switches to graphical mode if it needs to
66 download anything from the network (unless DISPLAY is not set).
69 \fB-d\fP, \fB--download-only\fP
70 Download any needed files, but stop before actually running the program.
73 \fB-D\fP, \fB--dry-run\fP
74 Just print what actions would be taken.
77 \fB-f\fP, \fB--feed\fP
78 Register (or unregister) an additional source of implementations. When you get
79 a CVS version of a project, it may contain an interface XML file. To add this
80 version to the list of available versions, use --feed on this XML file. The
81 file is not copied, so you don't need to re-add the file each time it is
84 Note that if you just want to run the program, you can invoke 0launch on the
85 interface file directly (without using --feed). This will force the injector to
86 use that version, but won't affect what happens when you run it using the URI
87 as normal. Use --feed when you want to use the CVS version even when using the
88 URI, or if the program is a library (and thus referenced by URI by other
91 Note also that the stability of CVS versions may be set to 'developer', in
92 which case you must set this as the preferred stability for the interface
97 Show the graphical policy editor. This allows you to select which version of
98 a program or library to use.
101 \fB-h\fP, \fB--help\fP
102 Show the built-in help text.
105 \fB-i\fP, \fB--import\fP
106 Import from files, not from the network. This is useful when testing an
107 interface file, to avoid uploading it to a remote server in order to download
108 it again. It might also be useful when installing from a CD or similar.
109 The file must have a trusted GPG digital signature, as when fetching from
110 the network. For unsigned interfaces, see --feed.
113 \fB-l\fP, \fB--list\fP
114 List all known interface (program) URIs. If a search term is given, only
115 URIs containing that string are shown (case insensitive).
118 \fB-m\fP, \fB--main=MAIN\fP
119 Run the specified executable instead of the default. If MAIN starts with '/'
120 then the path is relative to the implementation's top-level directory,
121 whereas otherwise it is relative to the directory containing the default
122 MAIN program. For example, if the default MAIN is \fBbin/svn\fP then
123 using \fB--main=svnadmin\fP will run \fB.../bin/svnadmin\fP instead.
126 \fB-o\fP, \fB--offline\fP
127 Run in off-line mode, overriding the default setting. In off-line mode, no
128 interfaces are refreshed even if they are out-of-date, and newer versions of
129 programs won't be downloaded even if the injector already knows about them
130 (e.g. from a previous refresh).
133 \fB-r\fP, \fB--refresh\fP
134 Fetch a fresh copy of all used interfaces. This will normally switch to GUI
135 mode, unless --console is also given. Note that using --refresh and --gui
136 together will check for updates to the GUI itself.
139 \fB-v\fP, \fB--verbose\fP
140 More verbose output. Use twice for even more verbose output.
143 \fB-V\fP, \fB--version\fP
144 Display version information.
