style='mso-spacerun:yes'>� </span>The project goal is targeted at providing a
C# interface to native <span class=SpellE>RRDtool</span> facilities through appropriate
.Net / Mono object model semantics with the intent of retaining an intuitive
syntax that fits naturally into the .Net / Mono paradigm and closely resembles
that of native <span class=SpellE>RRDtool</span>.<span
style='mso-spacerun:yes'>� </span>In doing so, <span class=SpellE>NHawk</span>
seeks to provide a powerful time series analysis toolkit library that fills a
big void in the .Net and Mono framework.<span style='mso-spacerun:yes'>�
</span>It is our hope to provide a toolkit that promotes high productively,
robustness, and expressiveness; enabling proficient C# developers to build code
interchangeably (and intuitively) with native <span class=SpellE>RRDtool</span>
script. It is a <span class=SpellE>NHawk</span> goal to promote productive use
by allowing clients to refer solely to native <span class=SpellE>RRDtool</span>
documentation resources, and thereby carry a very short learning curve (in most
cases if the developer is familiar with both <span class=SpellE>RRDtool</span>
and C#). The example code snippets that follow will hopefully illustrate the
basic concepts.<span style='mso-spacerun:yes'>� </span>Please make particular
note of syntactic similarities, and pay special attention to the section
highlighting serialization, <span class=SpellE>deserialization</span>, and <span
class=SpellE>deepcloning</span>, as these comprise powerful architectural
utility which include support for web service oriented applications as well as
for generation of, and interoperation with existing (native) <span
class=SpellE>RRDtool</span> scripts. <o:p></o:p></span></p>
