 # Perforce options, comme ca:
 #   compdef _perforce p4reopen=p4-job-global
 #
+# Anything more complicated should be modelled on one of the
+# _perforce_cmd_* handlers below.  To get this to work, the full
+# set of _perforce functions must be loaded; because of the way
+# autoloading works, a trick is required:  call "_perforce -l" which
+# causes the function to be executed, loading all the associated
+# functions as a side effect, but tells _perforce to return without
+# generating any completions.  For example, here is the completion
+# for my `p4desc' function which is an enhanced version of `p4 describe'
+# (without any handling for global Perforce arguments):
+#
+#  #compdef p4desc
+#
+#  _perforce -l
+#
+#  _arguments -s : \
+#    '-d-[select diff option]:diff option:((b\:ignore\ blanks c\:context d\:basic\ diff n\:RCS s\:summary u\:unified w\:ignore\ all\ whitespace))' \
+#    '-s[short form]' \
+#    '-j[select by job]:job:_perforce_jobs' \
+#    '*::change:_perforce_changes'
+#
+# To add handling of global options to this, see the end of the _perforce
+# function below.  Something like:
+#
+#   local -a _perforce_global_options _perforce_option_dispatch
+#   if _perforce_global_options; then
+#     _arguments -s : $_perforce_option_dispatch \
+#       '<other stuff>'
