# Running commands. All run* methods return an array. That can mean one line of
# output per array element, or in tagged/parse_forms mode, that can mean an
# array of hashes. 
#
# By default a P4Exception is raised if any errors or warnings are encountered 
# during command execution. You can also opt to have exceptions raised only
# for errors (and not warnings), or not at all by setting the exception level.
# The available levels are:
#
#     0 - Exceptions disabled
#     1 - Exceptions for errors
#     2 - Exceptions for errors and warnings
#
# For example:
#
#    p4.exception_level( 1 )
#
# You can fetch the results of the command from within a rescue block
# by calling P4#output; the errors with P4#errors and the warnings with
# P4#warnings

# "p4 user -o" with "parse_forms" enabled produces an array with a single
# hash entry.

# Now that we have the user's details, we can update them. Since this
# example is invasive, it's commented out by default.

#  p4.run( "user", "-i" )

#*******************************************************************************
# You can also run Perforce commands by invoking the method "run_<command>"
# rather than passing the command name as an argument to the run method. For
# example

#*******************************************************************************
# There are also shortcut methods to make form editing easy. Any method 
# taking the form "fetch_<command>" is equivalent to running "p4 <command> -o"
# and likewise any method taking the form "save_<command>" is equivalent to
# running "p4 <command> -i". These methods do not return an array - they 
# return only one element, since that's all that Perforce will return to you.
#
# Note that all of the "save*" methods require an argument. The argument
# can be either a string containing the edited form, or if you're using
# parse_forms() mode, then it can be the edited hash returned from a previous
# "fetch*" call.
