 The number of scripts made it difficult to know which scripts to use.  If you added the `bin/`
directory to your 
 `PATH`, it could add unecessary commands to your PATH or cause commands to be overriden due
generic names
-(like 'start-all.sh'). The number of scripts were reduced using the following methods:
+(like 'start-all.sh'). The number of scripts were reduced by removing scripts that are no
longer used and combining
+scripts with similiar functionality.
 
-* Scripts that are only called by other scripts were moved to a new `libexec/` directory
in the Accumulo binary tarball
-* Scripts with similiar functionality were combined
-* Extra/optional scripts were move to a new `contrib/` directory in the binary tarball

 Below are some notes on this change:
 
-* The 'accumulo' script was left alone except for improved usage and the addition of 'create-config'
and 'build-native'
-  commands to replace 'bootstrap_config.sh' and 'build_native_library.sh'.
+* The 'accumulo' script was mostly left alone except for improved usage.
 * The 'accumulo-service' script was created to manage Accumulo processes as services
 * The 'accumulo-cluster' command was created to manage Accumulo on cluster and replaces 'start-all.sh'
and 'stop-all.sh'.
-* All optional scripts in `bin/` were moved to `contrib/`:

-      $ ls accumulo-2.0.0/contrib/
-      bootstrap-hdfs.sh  check-tservers  gen-monitor-cert.sh  tool.sh
+* The 'accumulo-util' command combines many utility scripts such as 'build_native_library.sh',
'tool.sh', etc into one script.
