/**
* Filename : tyl-converter.php
* Author : Dark Neo with modifications by Laird.
* Description: Imports into the Thank You/Like System plugin the likes of
* either the SimpleLikes[1] plugin or the Thanks[2][3] plugin.
* Author : Dark Neo and martec; combined and refactored by Laird.
* Description: Imports into the Thank You/Like System plugin either the
* thanks/likes of the SimpleLikes[1] plugin or the Thanks[2][3]
* plugin, or the reputations of the core reputation system, the
* latter of which supports migration from the MyLikes[3] plugin.

* [2] https://community.mybb.com/mods.php?action=view&pid=82
* [3] https://community.mybb.com/mods.php?action=view&pid=188.
* Usage : Install the Thank You/Like System plugin in both the filesystem
* and via the ACP Plugins page, then move this file into your MyBB
* forum's root directory and browse to it. After the conversion
* completes, remove this file from your forum's root directory.
* Original Description[3]: Thanks SaeedGh & Thank You MyBB System Converter
* [3] Prior to Laird's mods.
* board's root directory and browse to it, appending to its
* address in the address bar one of:
* ?from=thanks (to convert from the Thanks plugin)
* ?from=simplelikes (to convert from the SimpleLikes plugin).
* ?from=reputation (to convert from core reputations).
* If you do not append any of the above, the script will attempt
* to auto-detect the plugin from which you are migrating, but for
* safety, it will not auto-detect the core reputation system as a
* source, so in that case the ?from=reputation is required.
* After the conversion completes, remove this file from your
* forum's root directory.
* Original Description[4]: Thanks SaeedGh & Thank You MyBB System Converter
* [4] Prior to martec's additions and Laird's modifications.
