do "pear help shortcuts" to see what shortcuts exist
* renamed "list-installed" command to "list" and made it able to
list the contents of installed packages as well as tar/tgz/xml files
* added some more/better command docs
* fixed up the synopsis part in the help output
* display option parameters (--foo=bar, where bar is specified in
'shortarg' as for example 'f:bar')
* renamed list-remote-packages to list-remote
* renamed remote-package-info to remote-info
- user interface abstraction, making a Gtk installer should only be
a matter of implementing PEAR_CommandUI_Gtk plus a "pear-gtk" executable
- separated code into command classes, able to specify one or more
commands
- no more "pear-get" :-)
* fixed use of PEAR_Config::singleton to avoid object copying
