## <#GAPDoc Label="Obsolete">
## Over time, the interface of &Polycyclic; has changed. This
## was done to get the names of &Polycyclic; functions to agree with the
## general naming conventions used throughout GAP. Also, some &Polycyclic;
## operations duplicated functionality that was already available in
## the core of GAP under a different name. In these cases, whenever possible
## we now install the &Polycyclic; code as methods for the existing GAP
## operations instead of introducing new operations.
## <P/>
## For backward compatibility, we still provide the old, obsolete
## names as aliases. However, please consider switching to the new names
## as soon as possible. The old names may be completely removed at some
## point in the future.
## <P/>
## The following function names were changed.
