TRace Plot Realtime (trpr) Distribution     OVERVIEW:This directory contains the source code and documentationfor the "trpr" program which allows a graphical display ofthe quantity of network traffic captured over time with aninstance of the popular "tcpdump" tool.  "Trpr" has filteroptions and can display plots for different "flows" of data(defined by protocol type, source, and destination).  Itis designed to be used with the "gnuplot" plotting program.With the "drec" option or "ns" option , "trpr" will also process log files from  the "drec" program from the MGEN toolset or provide analyses of "ns" (Berkeley's network simulator) trace files.FILES:README.TXT  - this file.trpr.cpp    - C++ source code for the "trpr" programtrpr.html   - HTML build instructions and user's guide.hcat.cpp    - C++ source code for "hcat", the histogram              concatenation program.TO BUILD:gcc -o trpr trpr.cpp -lmgcc -o hcat hcat.cpp -lmHCAT Usage:The Histogram Concatenator ("hcat") is useful for post-processingthe histogram output produced by "trpr".  "hcat" can be used to combine multiple histograms and to retrieve some summary statisticsfrom the histogram data.  Usage: hcat [normalize] [percent [<rangeMin>:]<rangeMax>] file1 [file2 file3 ...]Options:normalize  - The minimum bin is adjusted to correspond to zero.  Other             bins are correspondingly linearly adjusted.             percent [<rangeMin>:]<rangeMax> - Calculates the percentage of data                                  points lying in the specified range.                                  The <files> are expected to contain histogram data in pairs of data in  theorder of minimum bin to maximum bin, with the first value of the pairspecifying the bin and the second value specifying the number of datapoints for that histogram bin.
