-TODO:
-==============
-
-- Consider using Apache Commons Exec to replace SystemCommand?
-
-- Allows to specify a velocity-tools.properties or equivalent in classpath
-  root (e.g. classes/ folder) to define custom classes/tools to be used 
-  by Velocity.
-
-- Upgrade to Commons Configuration 2.x
-- Upgrade to Apache Velocity 2.x when available in Maven.
-
-    - See after upgrading above two if we can get rid of 
-      Commons Collections 3.x and Commons Lang 2.x 
-
-- Upgrade to slf4j.
-
-- Modify Jar copier to handle cases where snapshot are timestamped instead and
-  not being considered the latest when they should.  Like:
-  norconex-commons-lang-1.13.0-20170328.184247-17.jar vs 
-  norconex-commons-lang-1.13.0-SNAPSHOT.jar
-  https://github.com/Norconex/collector-http/issues/331#issuecomment-290196986
-
-- Redo DurationUtil to be more flexible (using fluid builder approach.
-  or check Apache or Java 8 equivalent classes if they can be made as flexible.
-  Look at:
-    https://commons.apache.org/proper/commons-lang/javadocs/api-3.5/index.html?org/apache/commons/lang3/time/DurationFormatUtils.html
-    http://docs.oracle.com/javase/8/docs/api/java/time/format/DateTimeFormatterBuilder.html
-    http://joda-time.sourceforge.net/apidocs/org/joda/time/format/PeriodFormatterBuilder.html
