     # == What is Optimistic Locking
     #
     # Optimistic locking allows multiple users to access the same record for edits, and assumes a minimum of
-    # conflicts with the data.  It does this by checking whether another process has made changes to a record since
-    # it was opened, an ActiveRecord::StaleObjectError is thrown if that has occurred and the update is ignored.

     # == Usage
     #
-    # Active Records support optimistic locking if the field <tt>lock_version</tt> is present.  Each update to the
-    # record increments the lock_version column and the locking facilities ensure that records instantiated twice
-    # will let the last one saved raise a StaleObjectError if the first was also updated. Example:
+    # Active Records support optimistic locking if the field +lock_version+ is present. Each update to the
+    # record increments the +lock_version+ column and the locking facilities ensure that records instantiated twice
+    # will let the last one saved raise a +StaleObjectError+ if the first was also updated. Example:

     #   p1 = Person.find(1)
