#%NAME% Macros for a the use of the FlexCurrent (orion:10000/sr/comploop/...)
# device as a macro motor and/or macro counter.
#%DESCRIPTION%
# The macros provide users with an interface between SPEC and the FlexCurrent
# (orion:10000/sr/comploop/... device.
#%INTERNALS%
# You may declare a motor and a counter, even for the same
# device! The macro motor/counter macros can handle that.
#%BR% %BR%Now declare a %B%motor\0controller%B%:
