# Workflow:
# C=git commit ;  A=git amend ; U=update_version ; P=opam pack
# - to make sure the sha and the version are good, one should never
#   do U and then A.
# - to make sure gtit is not confused, one should never do A and the P
#
# thereforeto avoid such problems, legal trace are defined by this automata:
# 0 -C-> 1
# 1 -A-> 1
# 1 -P-> 2
# 2 -U-> 0
# 1 -U-> 0
# to implement such a workflow, C puts a lock (state 1) and U removes it (state 0)
