-COMMAND NAME: gpcheck
-
-Verifies and validates Greenplum Database platform settings.
-
-*****************************************************
-SYNOPSIS
-*****************************************************
-
-gpcheck {{-f | --file} <hostfile_gpcheck> | {-h | --host} <host_ID>
-     | --local } [-m <master_host>] [-s <standby_master_host>] 
-     [--stdout | --zipout] [--config <config_file>]
-
-gpcheck --zipin <gpcheck_zipfile>
-
-gpcheck -?
-
-gpcheck --version
-
-
-*****************************************************
-DESCRIPTION
-*****************************************************
-
-The gpcheck utility determines the platform on which you are running 
-Greenplum Database and validates various platform-specific configuration 
-settings. gpcheck can use a host file or a file previously created with 
-the --zipout option to validate platform settings. At the end of a 
-successful validation process, GPCHECK_NORMAL message displays. If 
-GPCHECK_ERROR displays, one or more validation checks failed. You can 
-use also gpcheck to gather and view platform settings on hosts without 
-running validation checks. 
-
-Greenplum recommends that you run gpcheck as root. If you do not run 
-gpcheck as root, the utility displays a warning message and will not be 
-able to validate all configuration settings; Only some of these settings 
-will be validated. 
-
-
-*****************************************************
-OPTIONS
-*****************************************************
-
---config <config_file>
-
- The name of a configuration file to use instead of the default file 
- $GPHOME/etc/gpcheck.cnf. This file specifies the OS-specific checks to 
- run. 
-
-
-{-f | --file} <hostfile_gpcheck> 
-
- The name of a file that contains a list of hosts that gpcheck uses to 
- validate platform-specific settings. This file should contain a single 
- host name for all hosts in your Greenplum Database system (master, 
- standby master, and segments). gpcheck uses SSH to connect to the hosts. 
-
-
-{--h | --host} <host_ID> 
-
- Checks platform-specific settings on the host in your Greenplum Database 
- system specified by <host_ID>. gpcheck uses SSH to connect to the host. 
-
-
---local 
-
- Checks platform-specific settings on the segment host where gpcheck is 
- run. This option does not require SSH authentication. 
-
-
--m <master_host> 
-
- This option is deprecated and will be removed in a future release. 
-
-
--s <standby_master_host>
-
- This option is deprecated and will be removed in a future release. 
-
-
---stdout 
-
- Display collected host information from gpcheck. No checks or 
- validations are performed. 
-
-
---zipout 
-
- Save all collected data to a .zip file in the current working directory. 
- gpcheck automatically creates the .zip file and names it 
- gpcheck_<timestamp>.tar.gz. No checks or validations are performed. 
-
-
---zipin <gpcheck_zipfile> 
-
- Use this option to decompress and check a .zip file created with the 
- --zipout option. gpcheck performs validation tasks against the file you 
- specify in this option. 
-
-
--? (help) 
-
- Displays the online help. 
-
-
---version 
-
- Displays the version of this utility. 
-
-
-*****************************************************
-EXAMPLES
-*****************************************************
-
-Verify and validate the Greenplum Database platform settings by entering 
-a host file: 
-
- # gpcheck -f hostfile_gpcheck 
-
-Save Greenplum Database platform settings to a zip file: 
-
- # gpcheck -f hostfile_gpcheck --zipout 
-
-Verify and validate the Greenplum Database platform settings using a zip 
-file created with the --zipout option: 
-
- # gpcheck --zipin gpcheck_timestamp.tar.gz 
-
-View collected Greenplum Database platform settings: 
-
- # gpcheck -f hostfile_gpcheck --stdout

-            <p>The <codeph>gpcheck</codeph> utility determines the platform on which you are running
-                Greenplum Database and validates various platform-specific configuration settings.
-                    <codeph>gpcheck</codeph> can use a host file or a file previously created with
-                the <codeph>--zipout</codeph> option to validate platform settings. At the end of a
-                successful validation process, <codeph>GPCHECK_NORMAL</codeph> message displays. If
-                    <codeph>GPCHECK_ERROR</codeph> displays, one or more validation checks failed.
-                You can use also <codeph>gpcheck</codeph> to gather and view platform settings on
-                hosts without running validation checks.</p>
-            <p>You should run <codeph>gpcheck</codeph> as <codeph>root</codeph>.
-                If you do not run <codeph>gpcheck</codeph> as <codeph>root</codeph>, the utility
-                displays a warning message and will not be able to validate all configuration
-                settings; Only some of these settings will be validated.</p>
