[TxMt] find-file-in-project-and-load command wanted

[Bert Fitié]

Could the list help me with the following: I like to have a command  
that, when activated with the caret in a (unique) file-in-project  
name, finds this file and loads it automatically in textmate.

The function I'm looking for is comparable to that offered by the  
txmt URI with 2 differences: (1) with the txmt URI any text file can  
be loaded (I only want a file from my textmate project) and (2) the  
full path and file name needs to be specified (I only want to give  
the file name).

Any help is appreciated.
