SETUP
=====

Create the database tables used in this plugin, replacing the 'modx_' prefix with
the prefix that you are currently using:

CREATE TABLE `rev_site_content` LIKE `modx_site_content`;

ALTER TABLE rev_site_content CHANGE `id` `id` INT(10) DEFAULT NULL;

ALTER TABLE rev_site_content DROP PRIMARY KEY;

CREATE TABLE rev_site_tmplvar_contentvalues LIKE modx_site_tmplvar_contentvalues;

ALTER TABLE rev_site_tmplvar_contentvalues MODIFY id INT(10) DEFAULT NULL;

ALTER TABLE rev_site_tmplvar_contentvalues DROP PRIMARY KEY;

CREATE TABLE rev_site_modules LIKE modx_site_modules;

ALTER TABLE `rev_site_modules` CHANGE `id` `id` INT( 11 ) NOT NULL;

ALTER TABLE `rev_site_modules` CHANGE `createdon` `createdon` INT( 20 ) NOT NULL DEFAULT '0';

ALTER TABLE `rev_site_modules` CHANGE `editedon` `editedon` INT( 20 ) NOT NULL DEFAULT '0';

ALTER TABLE rev_site_modules DROP PRIMARY KEY;

CREATE TABLE rev_site_htmlsnippets LIKE modx_site_htmlsnippets;

ALTER TABLE `rev_site_htmlsnippets` CHANGE `id` `id` INT( 11 ) NOT NULL;

ALTER TABLE `rev_site_htmlsnippets` DROP PRIMARY KEY;

CREATE TABLE rev_site_plugins LIKE modx_site_plugins;

ALTER TABLE `rev_site_plugins` CHANGE `id` `id` INT( 11 ) NOT NULL;

ALTER TABLE `rev_site_plugins` DROP PRIMARY KEY;

CREATE TABLE rev_site_snippets LIKE modx_site_snippets;

ALTER TABLE `rev_site_snippets` CHANGE `id` `id` INT( 11 ) NOT NULL;

ALTER TABLE `rev_site_snippets` DROP PRIMARY KEY;

CREATE TABLE rev_site_templates LIKE modx_site_templates;

ALTER TABLE `rev_site_templates` CHANGE `id` `id` INT( 11 ) NOT NULL;

ALTER TABLE `rev_site_templates` DROP PRIMARY KEY;

CREATE TABLE `rev_site_tmplvars` LIKE `modx_site_tmplvars`;

ALTER TABLE `rev_site_tmplvars` CHANGE `id` `id` INT( 11 ) NOT NULL;

ALTER TABLE `rev_site_tmplvars` DROP PRIMARY KEY;

Create a new plugin through the manager and then copy and paste the contents of
the revision.php file. DO NOT include the <?php tags. The plugin must run from
the database or else it will not pick up the On*FormRender event.

Create the following directory and place the revision.php file along with a
.htaccess file for security reasons.

/assets/plugins/revision
