This package contains the libodbcinst library from unixodbc, a library used by odbc drivers for reading their configuration settings from /etc/odbc.ini and ~/.odbc.ini. it is useful to provide this in a stand-alone package, so that all odbc drivers in debian can use a consistent ini library, regardless of whether applications are built with iodbc or unixodbc.
also contained in this package are the driver setup plugins, which describe the features supported by individual odbc drivers.
