Iroki is all about mapping files, so we try to make them as simple to use as possible.
Here is an example mapping file. It's just a sweet screenshot of a spreadsheet.
Mapping files should be tab-delimited. We reccomend making your mapping file in your favorite spreadsheet program and then exporting it as a tab-delimited text file (tsv). Right click here and select Download to get the above mapping file as a tab seperated text file.
Note that Iroki will strip off whitespace from the beginning and end of all tokens in the mapping file.
