 | |
|  * Description: Various things to make admins' lives easier
 | |
|  * Documentation:
 | |
|  *  <p>Lowercase all tags:
 | |
|  *  <br>Set all tags to lowercase for consistency
 | |
|  *  <p>Recount tag use:
 | |
|  *  <br>If the counts of images per tag get messed up somehow, this will reset them
 | |
|  *  <p>Purge unused tags:
 | |
|  *  <br>Get rid of all the tags that don't have any images associated with
 | |
|  *  them (normally they were created as typos or spam); this is mostly for
 | |
|  *  neatness, the performance gain is tiny...
 | |
|  *  <p>Convert to InnoDB:
 | |
|  *  <br>Convert your database tables to InnoDB, thus allowing shimmie to
 | |
|  *  take advantage of useful InnoDB-only features (this should be done
 | |
|  *  automatically, this button only exists as a backup). This only applies
 | |
|  *  to MySQL -- all other databases come with useful features enabled
 | |
|  *  as standard.
 | |
|  *  <p>Database dump:
 | |
|  *  <br>Download the contents of the database in plain text format, useful
 | |
|  *  for backups.
