# Filter::tee(3pm)

tee source filter

## 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.
