## List of known Etheroum forks
## ============================
##
## See `here <../../ex/vm/interpreter/forks_list.html>`_ for an
## overview.
##
## Assumptions on the naming of the fork list:
##  * each symbol start with the prefix "Fk"
##  * the first word of the prettified text representaion is the same
##    text as the one following the "Fk" in the symbol name (irrespective
##    of character case.)
