## Commands:
* _list_:
List pull requests in the current project.
* _checkout_:
Check out the head of a pull request in a new branch.
## Options:

Display pull requests with state <STATE> (default: "open").
-f, --format <FORMAT>
Pretty print the list of pull requests using format <FORMAT> (default:
"%sC%>(8)%i%Creset %t% l%n"). See the "PRETTY FORMATS" section of the
git-log manual for some additional details on how placeholders are used in
format. The available placeholders are:
%I: pull request number
%i: pull request number prefixed with "#"
%U: the URL of this pull request
%S: state (i.e. "open", "closed")
%sC: set color to red or green, depending on pull request state.
%t: title
%l: colored labels
%L: raw, comma-separated labels
%b: body
%B: base branch
%H: head branch
%au: login name of author
%as: comma-separated list of assignees
%Mn: milestone number
%Mt: milestone title
%NC: number of comments
%Nc: number of comments wrapped in parentheses, or blank string if zero.
%cD: created date-only (no time of day)
%cr: created date, relative
%ct: created date, UNIX timestamp
%cI: created date, ISO 8601 format
%uD: updated date-only (no time of day)
%ur: updated date, relative
%ut: updated date, UNIX timestamp
%uI: updated date, ISO 8601 format
-o, --sort <SORT_KEY>
Sort displayed issues by "created" (default), "updated", "popularity", or "long-running".
-^ --sort-ascending
Sort by ascending dates instead of descending.
-L, --limit <LIMIT>
Display only the first <LIMIT> issues.
