[description]
[para]
The [package tcl::transform::limitsize] package provides a command
creating a channel transformation which limits the number of
characters which can be read from the channel. A generator for an
artificial EOF.
[para] The internal [package TclOO] class implementing the transform
handler is a sub-class of the [package tcl::transform::core]
framework.

[list_begin definitions]
[call [cmd ::tcl::transform::limitsize] [arg chan] [arg max]]
This command creates a size limiting transformation on top of the
channel [arg chan] and returns its handle.
[para] [arg max] is the number of bytes which can be read from the
channel before EOF is signaled by the transformation. Note that
popping the transformation clears the EOF it generated as well.
