Filter::tee - tee source filter


    use Filter::tee 'filename' ;
    use Filter::tee '>filename' ;
    use Filter::tee '>>filename' ;


This filter copies all text from the line after the "use" in the current source file to the file specified by the parameter "filename".

By default and when the filename is prefixed with a '>' the output file will be emptied first if it already exists.

If the output filename is prefixed with '>>' it will be opened for appending.

This filter is useful as a debugging aid when developing other source filters.
