==========

Selection of utilities for poking around with EPICS records

* `ophyd.Device`s for most EPICS record types with sensible attribute names

* Give a record name, get a device instance for that record

With the help of graphviz

* Graph record input, output, and forward links

* Graph areaDetector port plugin sources

Record in/out/forward link graphing

-----------------------------------

AreaDetector port graphing

Record example

--------------

```python

import recordwhat

rec = recordwhat.get_record_by_name('XF:31IDA-OP{Tbl-Ax:X1}Mtr', read_attrs=[])

# get a specific field's value

print('steps_per_revolution =', rec.steps_per_revolution.get())

# or access to the signal itself

print('steps_per_revolution signal =', rec.steps_per_revolution)

print()

# or ask for *all* the values

print(rec.get())

```

[Full source](examples/motor.py)

Output:

```python

steps_per_revolution = 200

steps_per_revolution signal = EpicsSignal(read_pv='XF:31IDA-OP{Tbl-Ax:X1}Mtr.SREV', 

                                          parent='XF:31IDA-OP{Tbl-Ax:X1}Mtr', value=200, 

                                          timestamp=1455045145.501072, pv_kw={}, auto_monitor=False, 

                                          string=False, write_pv='XF:31IDA-OP{Tbl-Ax:X1}Mtr.SREV',

                                          limits=False, put_complete=False)

MotorRecordTuple(alarm_acknowledge_severity=0, alarm_acknowledge_transient=1,

                 access_security_group='', description='Delta',

                 scan_disable_input_link_value=0, disable_putfields=0,

                 # (... a bunch of lines clipped...)

                 seconds_to_velocity=0.2, soft_channel_position_lock=0,

                 speed_revolutions_sec=0.5, startup_commands='', status_update=0,

                 steps_per_revolution=200, tweak_step_size_egu=1.0, use_encoder_if_present=0,

                 use_rdbl_link_if_presen=0, user_direction=0, velocity_egu_s=0.1)
