Migrating from SVN to Fossil requires an intermediary trip through GIT.
Much of the code to do this was cribbed from instructions on sqlite.org. link.

fossilusers='users.txt'
# parameters:
# 1 - username of admin
# 2 - svn repository to convert
# 3 - name of fossil repo
# note: the repository will be created right here!
