saltkey

Working with header keys.

Note

Perhaps this module needs to be depricated. Most of it’s code seems to be dedicated to hiding nice error handling behind ugly status returns. Please convert all code that depens on it to use salterror and saltsafeio instead.

Todo

Clean up module to use proper error handling and remove unnecesary code.
