+CONSOLE APPLICATION : fileopenwrite Project Overview
+====================================================
+## Overview 
+Test program to verify LogStash Windows issue.  This program attempts to opens a file with SharedMode=0(Exclusive lock)
+and writes a log message a couple times
+
+The test attempts to creat/open a file with an exclusive OS lock, write  to the file and close.
+The test then attempts to delete the file from disk.
+
+## Instructions
+
+To run the test first verify the logstash monolithic jar exists in the current directory
+
+Run the logstash.cmd
+```bat
+c:\>cd \git\fileopenwrite
+c:\git\fileopenwrite>logstash.cmd
+```
+
+Once logstash has finished opening test by entering a message in stdin.
+
+Now open a new shell.
+
+```bat
+c:\>cd \git\fileopenwrite
+c:\git\fileopenwrite>fileopenwrite.cmd
+```
+
+
+## Output from logstash.bat
+```bat
+
+C:\git\fileopenwrite>c:
+
+C:\git\fileopenwrite>cd \git\fileopenwrite
+
+C:\git\fileopenwrite>rem set HOME=c:\git\fileopenwrite\sincedb
+
+C:\git\fileopenwrite>rem set CloseAfterRead=true
+
+C:\git\fileopenwrite>"c:\Program Files\Java\jre7\bin\java.exe" -jar logstash-1.1.10.dev-monolithic2.jar agent -f logstash.conf
+start
+{
+         "@source" => "stdin://RI-ENG-229/",
+           "@tags" => [],
+         "@fields" => {},
+      "@timestamp" => "2013-05-02T21:11:42.241Z",
+    "@source_host" => "RI-ENG-229",
+    "@source_path" => "/",
+        "@message" => "start",
+           "@type" => "human"
+}
+{
+       "@source" => "file://RI-ENG-229/C:\\git\\fileopenwrite\\blocked.log",
+         "@tags" => [],
+       "@fields" => {},
+    "@timestamp" => "2013-05-02T21:11:59.642Z",
+      "@message" => "to write to the file.\r",
+         "@type" => "blocked"
+}
+```
+
+
+
+## Output from fileopenwrite.bat
+```bat
+C:\git\fileopenwrite>rm blocked.log
+'rm' is not recognized as an internal or external command,
+operable program or batch file.
+
+C:\git\fileopenwrite>echo fileopenwrite will write n messages to the log file starting from position 0

+
+Writing 46 bytes to blocked.log.
+Wrote 46 bytes to blocked.log successfully.

+C:\git\fileopenwrite>echo Now start the logstash.cmd
+Now start the logstash.cmd
+
+C:\git\fileopenwrite>pause
+Press any key to continue . . .
+
+C:\git\fileopenwrite>Debug\fileopenwrite.exe blocked.log 3
+
+ERROR: CreateFile failed with error code 32 as follows:
+The process cannot access the file because it is being used by another process.
+
+Terminal failure: Unable to open file "blocked.log" for write.
+
+C:\git\fileopenwrite>echo Deleting the log file
+Deleting the log file
+
+C:\git\fileopenwrite>pause
+Press any key to continue . . .
+
+C:\git\fileopenwrite>del blocked.log
+C:\git\fileopenwrite\blocked.log
+The process cannot access the file because it is being used by another process.
+
+C:\git\fileopenwrite>pause
+Press any key to continue . . .
+```
+
+# Conclusion
+The output from the fileopenwrite.bat file clearly does not exhibit the correct behavior.
+The Errors
+
+> ERROR: CreateFile failed with error code 32 as follows:
+> The process cannot access the file because it is being used by another process.
+
+And 
+> The process cannot access the file because it is being used by another process.
+
+Show that log stash does not release the file reader lock until the process stops running.
+Rolling log appenders and loggers that attempt to obtain exclusive access will fail to operate properly when logstash monitors them.
