ProcessTemplate/ProcessTemplate.psm1

<#

.SYNOPSIS
    Imports a process template definition from disk.
    
.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.
