Export and Import Work item queries in TFS projects

I have lately been introducing new WorkItemTypes in our TFS project to handle tests and support cases. With those new types the need for modifying the queries in the current projects was necessary. To modify a query I could have opened them in visual studio and saved them to disk and then saved them individually to each project. Since we are getting a lot of projects (60+) this would be a quite tedious task to update 10+ queries in each project individually.
To solve this administrative plague I wrote a small commandline program that allows you to export and import queries from a project.

Example
To list all queries in a project
TFSQueryUtil.exe /t https://tfsserver.domain.com:8143 /p "My Tfs Project"

This will list every Work Item Query by Scope, Name and description

To export all queries to the current folder
TFSQueryUtil.exe /t https://tfsserver.domain.com:8143 /p "My Tfs Project" /o Export /q *

This will export each query using the name of the query (plus the .wiq extension) as name of the exported file. If you want to only export one query, use the example below.
TFSQueryUtil.exe /t https://tfsserver.domain.com:8143 /p "My Tfs Project" /o Export /q "My query"

To import all *.wiq files to a project as Team queries
TFSQueryUtil.exe /t https://tfsserver.domain.com:8143 /p "My Tfs Project" /o Import /f *.wiq /qs Public

This command will use the filename (without the .wiq extension) as name for the imported query.
You can also specify a Description of the query by using the /qd switch (best for use with one query imports)

The format of the wiq files follows the WorkItemQuery schema but since the schema only includes the query and no meta data (like name, scope or description) this has to be provided as parameter switches... (Perhaps something to fix in TFS 2010)

If you need more help add the /? parameter.

I haven't released the program as open source but feel free to use it if you have need for it.
Can be downloaded from http://dan.meridium.se/TfsQueryUtil.rar
To use it you need to have Team Foundation Explorer 2008 installed. (needs the tfs dlls in the GAC).

* Now writes xml files as utf-8 (was an in consequence between xml notation and file encoding)
