Note:
The csv file must contain the headers written in red characters. The field separator is the Tab key.
As the headers are used to identify the data, the csv file may contain only a subset of these columns. For example, the csv file may contain only the following columns: "Label Purpose Description Author Relative_Path All_DB_Regexp"
