# Filter::tee - phpMan

## NAME
    [Filter::tee] - tee source filter

## SYNOPSIS
        use [Filter::tee] 'filename' ;
        use [Filter::tee] '>filename' ;
        use [Filter::tee] '>>filename' ;

## DESCRIPTION
    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.
