# Commands
##############################################################################
# Command structure explanation
#
# Values in [] are optional
# Values in () are choices of fixed values; value in all caps is default
# Special (Iourta) == (IN|on|under|over|through|at) Note that some of the 
#     values can be missing to indicate limited options.  Capital value is the
#     default.
# Values in <> refer to objects or people
# | == or
# / == synonym
#
# Generally a command will follow one of the following formats:
#   verb
#   verb <target>
#   verb modifier <target>
#   verb <subject> modifier <target>
#
# Commands can be chained on one input by putting either '.' or ' THEN ' in
# between the commands.
# Examples: > x door.x room
#           > x door then x room
#
# TODO: Leaving out the subject or target will cause the parser to attempt to 
#       use the current object of attention.  
#       This goes along with pronoun processing.
#
# TODO: Implement ',' , "AND", "ALL", "ALL <type>" as multi-object linkers.
#
# TODO: Implement "keyring" concept for locking/unlocking things.
