+# netstat info
+
+Produce some netstat -an files for instance as follows:
+
+    netstat -an > netstat.1.info
+    sleep 10
+    netstat -an > netstat.2.info
+
+Now have the netstat-info jar file available:
+
+    curl -s -o netstat-info.jar https://github.com/stokpop/netstat-info/releases/download/1.0.0/netstat-info-1.0.0-all.jar
+
+Create a mapper file to map ip's to known names, for instance `netstat.mapper`:
+
+     127.0.0.1=localhost
+     1.2.3.4=my_laptop
+         
+Run netstat-info with the files:
+
+    java -jar netstat-info.jar report netstat.1.info netstat.mapper
+
+This will show a report like:
+
+    ========= Processing netstat.1.info =========
+
+    ==> Listen ports (15)
+    ..., 3633, 6395, 6434
+
+    === INCOMING ===
+
+    ==> Count per state (INCOMING)
+    I ESTABLISHED(3633)=1
+    I ESTABLISHED(6395)=2
+    I ESTABLISHED(6434)=1
+
+    ==> Count established per address and port (INCOMING)
+    I 192.168.1.125(6395)=1
+    I 192.168.1.205(6395)=1
+    I localhost(3633)=1
+    I localhost(6434)=1
+
+    === OUTGOING ===
+
+    ==> Count per state (OUTGOING)
+    O CLOSE_WAIT(443)=6
+    O ESTABLISHED(2553)=1
+    O ESTABLISHED(3633)=3
+    ...
+         
+You can also compare two files, and supply the portnumber to compare:
+
+    java -jar netstat-info.jar compare 443 netstat.1.info netstat.2.info netstat.mapper
+
+It will output something like:
+
+    ==> compare netstat.1.info and netstat.2.info
+    5.11.77.13(443)-my_laptop(52332) ESTABLISHED ==> ESTABLISHED
+    16.12.3.1(443)-my_laptop(52212) CLOSE_WAIT ==> CLOSE_WAIT
+    ...
+
+# directories
+
+When you supply directories instead of file names, all files in the directory will be walked
+and reports and/or compares are generated for all found netstat files. Example:
+
+    java -jar netstat-info.jar report netstat.1.info netstat.2.info netstat.mapper
+
+# build
+
+To build executable jar:
+
+    ./gradlew clean installShadowDist
+
+The jar is here:
+
+    ./build/libs/netstat-info-1.0-all.jar
+
+
