|
|
--accept-license <License> Set accepted license. Separate multiple values with ','
|
|
Command:

|
verify <Provider> ... : Verify program provider info.
|
|
add <Provider> ... : Add program provider info.
|
|
update: Update program info.
|
|
clear: Clear program info.
|
|
list: List available projects.
|
|
search <Name or Pattern> : Search projects by name
|
|
show <Project> : Show more info about project.

|
|
Notice:
|
|
License
|
|
By downloading and using Grab, you are indicating your agreement to MIT license. (https://github.com/Kiritow/OpenComputerScripts/blob/master/LICENSE)
|
|
All scripts in official OpenComputerScript repository are under MIT license.
|
|
Before downloading any package under other licenses, Grab will ask you to agree with it.
|
|
This confirmation can be skipped by calling Grab with --accept-license.
|
|
Example:
|
|
--accept-license=mit means MIT License is accepted.
|
|
--refuse-license=mit means MIT License is refused.
|
|
--accept-license means all licenses are accepted.
|
|
--refuse-license means all licenses are refused. (Official packages are not affected.)
|
|
If a license is both accepted and refused, it will be refused.
|
|
Program Provider
|
|
A package is considered to be official only if it does not specified repo and proxy. Official packages usually only depend on official packages.
|
|
You can also install packages from unofficial program provider with Grab, but Grab will not check its security.
|
|
Notice that override of official packages is not allowed.
