/**
|

|
|
* Parses string hash files. File format is as such:
|
||
|
|
*
|
||
|
|
* DefaultKeyValue
|
||
|
|
* KEY: Value
|
||
|
|
* KEY2: Value2
|
||
|
|
* --MULTILINE-KEY--
|
||
|
|
* Multiline
|
||
|
|
* value.
|
||
|
|
*
|
||
|
|
* Which would output something similar to:
|
||
|
|
*
|
||
|
|
* array(
|
||
|
|
* 'ID' => 'DefaultKeyValue',
|
||
|
|
* 'KEY' => 'Value',
|
||
|
|
* 'KEY2' => 'Value2',
|
||
|
|
* 'MULTILINE-KEY' => "Multiline\nvalue.\n",
|
||
|
|
* )
|
||
|
|
*
|
||
|
|
* We use this as an easy to use file-format for configuration schema
|
||
|
|
* files.
