+Introduction:
+
+ Nitpicker is simple, Nitpicker is efficient, Nitpicker is Open Source.
+ Nitpicker is the free IP Flow Accounter.
+ It started because the commercial accounting software was just not fast,
+ precise and reliable enough to fit a today's ISP / MSP requirements.
+
+Here are some of the large benefits of nitpicker above other accounting software:
+ - It is 100% free
+ - It is Public Domain.
+ - It is designed for speed
+ - It is designed to run reliable under djb's daemontools
+ - It consumes minimal processor power
+ - It also runs with little memory
+
+
+Description:
+
+ Nitpicker is (currently) running under *BSD and Linux.
+ It is designed for the berkley packet filter (BPF).
+ (Sun Solaris(c) packet filter is currently examined).
+ Linux doesn't have a device like the bpf,
+ so you need to have libpcap ( Notice: We strongly recommend using *BSD )
+ Nitpicker accesses the raw ethernet frames and reads the header informations.
+ Nitpicker will write the flows into a file when there are n flows in the savequeue.
+ They are moved there after n seconds passed since the flowstart
+ (This prevents never-ending flows like news to be written too)
+
+ The flowfile is called flow.<unixtimestamp>.u At the end of a dumping period,
+ the .u files will be renamed to *.s, and new .u files will be created
