- Each ``<moduleSpec>`` must be in one of the following formats::
-
- {moduleName} ... matches any version
- {moduleName}>={version} ... at least version <version> is required

- {moduleName}<={version} ... modules must not be newer than <version>
+ Each ``<moduleSpec>`` can be either a bare module name or it can be a
+ module name with a version constraint (operators ``=``, ``<``, ``>``,
