The general +SCR API allows <tt>Read()</tt> and <tt>Write()</tt> access to get and +change data. However, snapper agent currently provides only Read calls. + +<p> +<h2>Implementation</h2> +It is simple wrapper for libsnapper C++ library. The library initialization routines are used to read list of current snapshots and their data. +<p> +Each snapshot is described in YCPMap. Snapshot is identified by number. The map also contains the snapshot type (`SINGLE, `PRE, `POST) and the date of snapshot creation. SINGLE and PRE types of snapshot have the description string. The snapshot of PRE type contains number of relevant POST snapshot and vice versa. + +<P> +<i><b>Note:</b> The complete development documentation is available in the +<a href="autodocs/index.html"><tt>autodocs/</tt></a> directory.</i> + +<P> +<h2>Interface for snapper-agent</h2> +The interface is implemented as a SCR agent with the usual <tt>Read()</tt>, +<tt>Write()</tt> and <tt>Dir()</tt> interface.
