 # HumanTaskDistributor
 Simple command-line tool that helps automate the process of distributing sets of tasks to many people, including weighted preference and historical variation.

+## Help

+usage: HumanTaskDistributor
+ -hl,--humans-list <arg>                Path to a CSV file containing list
+                                        of humans to distribute tasks to.
+                                        First column should be the name of
+                                        the person, and second column can
+                                        be empty, or contain a
+                                        floating-point weight.
+ -o,--output <arg>                      Output file to write CSV
+                                        distribution data to.
+ -prev,--previous-distributions <arg>   One or more CSV files containing
+                                        previous task distribution
+                                        results, to aid in balancing
+                                        distribution over multiple
+                                        iterations. Each should be of the
+                                        form: person name, task name
+ -tl,--tasks-list <arg>                 Path to a CSV file containing list
+                                        of tasks that can be distributed
+                                        to humans. First column should be
+                                        unique task name.
