| 13 | # Shepherd is an attempt to reconcile many different tv_grab_au scripts and |
|---|
| 14 | # make one cohesive reliable data set. It works by calling a series of |
|---|
| 15 | # scripts that grab data from a large variety of sources, and then |
|---|
| 16 | # analysing the resulting XML data sets and determining which of the many |
|---|
| 17 | # is the most reliable. |
|---|
| 18 | |
|---|
| 19 | # Shepherd runs in 4 passes: |
|---|
| 20 | # pass 1: (app/shepherd) Checks that all components are up-to-date, auto- |
|---|
| 21 | # updates if not. |
|---|
| 22 | # Passes control onto shepherd |
|---|
| 23 | # pass 2: (engine/dog) calls grabbers to fill in missing data |
|---|
| 24 | # pass 3: (engine/dog) calls reconciler to reconcile overlapping data |
|---|
| 25 | # and normalize programme titles to our preferred title |
|---|
| 26 | # pass 4: (engine/dog) calls postprocessors to postprocess data |
|---|
| 27 | # (e.g. flag HDTV programmes, augment with IMDb etc.) |

| 29 | # Changelog: |
|---|
| 30 | # 0.2.31 : split tv_grab_au (install/test/upgrade/enable/disable) from |
|---|
| 31 | # shepherd (grab/reconcile/postprocess). Previous changelog history |
|---|
| 32 | # is in shepherd |
|---|
| 33 | # 0.3.0 : This split deserves a real version bump, Linc! :) |
|---|
| 34 | # 0.3.1 : honour $option_ready |
|---|
| 35 | # 0.3.10 : split out into apps directory, renamed back to 'shepherd' with |
|---|
| 36 | # an auto symlink to tv_grab_au |
|---|
| 37 | # logging to logs/ directory |
