libvte-dev 1:0.20.1-1ubuntu2 (amd64 binary) in ubuntu karmic

 The VTE library inserts terminal capability strings into a trie, and then
 uses it to determine if data received from a pseudo-terminal is a control
 sequence or just random data. The sample program "interpret" illustrates
 more or less what the widget sees after it filters incoming data.
 .
 This package contains development files for the VTE library and its
 Python bindings.
