rrdtool \- Round Robin Database Tool

order to make \fBRRDtool\fR work it is important to note that
\&\fBRRDtool\fR can be remotely controlled through a set of pipes. This
saves a considerable amount of startup time when you plan to make
-\&\fBRRDtool\fR do a lot of things quickly. Check the section on \*(L"Remote Control\*(R" further down. There is also a number of language bindings
-for RRDtool which allow you to use it directly from perl, python, tcl,
-php, etc.

+For very big setups, updating thousands of \s-1RRD\s0 files often becomes a serious \s-1IO\s0
