ComboStrap Administrative Commands


Example:
  * Replicate all pages into the database
```bash
php ./bin/plugin.php combo metadata-to-database --host serverHostName  --port 80 :
# or
php ./bin/plugin.php combo metadata-to-database --host serverHostName  --port 80 /
```
  * Replicate only the page `:namespace:my-page`
```bash
php ./bin/plugin.php combo metadata-to-database --host serverHostName  --port 80 :namespace:my-page
# or
php ./bin/plugin.php combo metadata-to-database --host serverHostName  --port 80 /namespace/my-page
```

Animal: If you want to use it for an animal farm, you need to set first the animal directory name in a environment variable
```bash
animal=animal-directory-name php ./bin/plugin.php combo
```
