"""Produce a report of visits which can move from one interval to another.

Usage:
do move_it [-[no]vcw] [-scenario_name=] [LRP]
start_check_interval end_check_interval [target_start_time] [target_end_time] [output_options]

where:
- -vcw/-novcw controls whether verified constraint windows are included when
determining schedulability. With -vcw, visits with verified contraint windows
intersecting the target interval will be included output to the move_it.rpt
file. With -novcw (the default), visits with only verified constraint windows
intersecting the target interval will be included in the stuck.rpt file.
- scenairo_name defaults to the default scenario name from relation constraint_scenarios
- LRP defaults to the latest released lrp
- start_check_interval, end_check_interval, target_start_time, target_end_time must
all be of the form yyyy.ddd:hh:mm:ss
- output_options can be 'm' for reporting visits which can move (file move_it.rpt)
or 'f' for reporting visits which cannot move (file stuck.rpt)
The default is to produce both files. The files are written
into the current working directory.

(The 'do' is not needed from the LRP account, just 'move_it ...' should work.)


Examples:
do move_it 2002.007 2002.021

Check for any visits not having plan windows in 007-021 which can move into 007-021
from the latest released LRP. Report both visits which can and cannot move with
separate summaries.

do move_it 01198A 2002.007 2002.021

Check for any visits not having plan windows in the specified interval which can
move into that interval from LRP 01198A. Produce both summary files.

do move_it 2002.161 2002.175 2002.007 2002.021

Check for visits with plan windows intersecting 161-175 which can move into 007-021
from the latest released LRP. Produce both summary files.

do move_it 01198A 2002.161 2002.175 2002.007 2002.021

Check for visits with plan windows intersecting 161-175 which can move into 007-021
from LRP 01198A. Produce both summary files.

do move_it 01198A 2002.161 2002.175 2002.007 2002.021 f

Check for visits with plan windows intersecting 161-175 which can move into 007-021
from LRP 01198A. Produce only the report showing visits which cannot move (stuck.rpt).

do move_it 01198A 2002.161 2002.175 2002.007 2002.021 m

Check for visits with plan windows intersecting 161-175 which can move into 007-021
from LRP 01198A. Produce only the report showing visits which can move (move_it.rpt).

Output is like that for the 'available' report except that for the visits that can
move (ie. those in the move_it.rpt file). For those visits, at the end of each line is
a 'w' if there were constraint windows for the target time interval, 'v' if there were
verified constraint windows for the interval, or 'wv' if there were both.
