This teacup subcommand is used to produce lists of packages, optionally restricting to just those that aren't installed or are in need of updates.
The command "teacup list --at-default" will list what is installed locally, without reference to the network.
teacup list ?--http-proxy HOST:PORT? ?-v? ?--timeout SEC? ?--at-default? ?--at DIR?
?--as profile|table|csv? ?--only uninstalled|unknown|newer|update? ?--is ENTITY? ?NAME ?VERSION??Lists all instances of the NAMEd package found in the configured set of archives. The output can be restricted to a specific VERSION of the package, or forced to contain all packages (by specifying neither NAME nor VERSION).
If a NAME was specified, but nothing was found the command does a case-insensitive substring search for candidate names and then re-does the operation for all found candidates. This fixes typos like 'bwidget' instead of 'BWidget', but also means that 'zlib' will find 'zlibtcl', etc.
