#csv-manipulation-tool A CSV-manipulation tool developed at Ellar Development for managing e-mail lists for our web-game Nordicmafia.

This tool is probably not compatible with most CSV-lists, and are primarly a tool for merging and subtracting emails from CSV's.

The tool works by taking a csv-document ("source") and another one ("input") and compare them to eachother (performing adjustments).

The source-document should only consist of one field, with header title "email".

Please read the code for better understanding.

##Installation npm install csv-manipulation-tool

##Options (flags)

Flag	Short	Description	Default value
--source	--s	Source-CSV file	null (required)
--input	--i	Input-CSV file	null (required unless action is "validate", only source is required then)

--target	--t	Input-CSV target header title	"email"
--action	--a	Action to perform. (join, subtract, validate)	"join"
