%description
libmodbus is a free software library to send/receive data with a device which
respects the Modbus protocol. This library can use a serial port or an Ethernet
connection.

This package ships both the shared library (libmodbus.so.5) and the development
files (C headers, pkg-config file and linker symlink) needed to build software
against libmodbus. It provides the rosdep dependency "libmodbus-devel"
(rosdep key libmodbus-dev) used by ROS packages such as at-sonde-ros-driver.
