Установка из командной строки

Actually, the options only show up with the relevant command, i.e if you do 'pear help install' you'll get every option supported by the install command.

For some reason command line flags do not seem appear to be documented in the online manual. Once PEAR is installed however, you can get a list of some (why not all?) of the flags using "pear help options". These include:

Options:
-v increase verbosity level (default 1)
-q be quiet, decrease verbosity level
-c file find user configuration in `file'
-C file find system configuration in `file'
-d foo=bar set user config variable `foo' to `bar'
-D foo=bar set system config variable `foo' to `bar'
-G start in graphical (Gtk) mode
-s store user configuration
-S store system configuration
-u foo unset `foo' in the user configuration
-h, -? display help/usage (this message)
-V version information

There also appears to be some extra undocumented ones though including:

--alldeps (seems obvious)

and

-f (no idea, referenced in the UNL_Event_Publisher documentation)
