libxi-dev 2:1.3-3ubuntu0.1 (amd64 binary) in ubuntu lucid

 libXi provides an X Window System client interface to the XINPUT
 extension to the X protocol.
 .
 The Input extension allows setup and configuration of multiple input devices,
 and will soon allow hotplugging of input devices; to be added and removed on
 the fly.
 .
 This package contains the development headers for the library found in
 libxi6. Non-developers likely have little use for this package.
