# A simple 'tee' implementation, using perl tie.
|
||
|
#
|
||
|
# Whenever you print to the handle, it gets forwarded to a list of
|
||
|
# handles. The list of output filehandles is passed to the constructor.
|
||
|
#
|
||
|
# This is similar to IO::Tee, but only used for output. Only the PRINT
|
||
|
# method is currently implemented; that's all we need. We don't want to
|
||
|
# depend on IO::Tee just for this.
