Git/Git.psm1

<#
 
.SYNOPSIS
    Gets information from one or more Git repositories in a team project.
 
.PARAMETER Project
    Specifies either the name of the Team Project or a previously initialized Microsoft.TeamFoundation.WorkItemTracking.Client.Project object to connect to. If omitted, it defaults to the connection opened by Connect-TfsTeamProject (if any).

For more details, see the Get-TfsTeamProject cmdlet.
 
.PARAMETER Collection
    Specifies either a URL/name of the Team Project Collection to connect to, or a previously initialized TfsTeamProjectCollection object.

When using a URL, it must be fully qualified. The format of this string is as follows:

http[s]://<ComputerName>:<Port>/[<TFS-vDir>/]<CollectionName>

Valid values for the Transport segment of the URI are HTTP and HTTPS. If you specify a connection URI with a Transport segment, but do not specify a port, the session is created with standards ports: 80 for HTTP and 443 for HTTPS.

To connect to a Team Project Collection by using its name, a TfsConfigurationServer object must be supplied either via -Server argument or via a previous call to the Connect-TfsConfigurationServer cmdlet.

For more details, see the Get-TfsTeamProjectCollection cmdlet.
