Each checkpoint is a block hash, representing a block on the blockchain + // that the network should reach consensus on. + // + // Besides verifying signatures of checkpoint messages, each node also verifies + // the consistency of the checkpoints. If a conflicting checkpoint is received, + // it means either the checkpoint master key is compromised, or there is an + // operator mistake. In this situation the node would discard the conflicting + // checkpoint message and display a warning message. This precaution controls + // the damage to network caused by operator mistake or compromised key. + // + // Operations + // + // Checkpoint master key can be established by using the 'makekeypair' command + // The public key in source code should then be updated and private key kept + // in a safe place. + // + // Any node can be turned into checkpoint master by setting the 'checkpointkey' + // configuration parameter with the private key of the checkpoint master key. + // Operator should exercise caution such that at any moment there is at most + // one node operating as checkpoint master. When switching master node, the + // recommended procedure is to shutdown the master node and restart as + // regular node, note down the current checkpoint by 'getcheckpoint', then + // compare to the checkpoint at the new node to be upgraded to master node. + // When the checkpoint on both nodes match then it is safe to switch the new + // node to checkpoint master. + // + // The configuration parameter 'checkpointdepth' specifies how many blocks + // should the checkpoints lag behind the latest block in auto checkpoint mode. + // A depth of 0 is the strongest auto checkpoint policy and offers the greatest + // protection against 51% attack. A negative depth means that the checkpoints + // should not be automatically generated by the checkpoint master, but instead + // be manually entered by operator via the 'sendcheckpoint' command. The manual + // mode is also the default mode (default value -1 for checkpointdepth). + // + // Command 'enforcecheckpoint' and configuration parameter 'checkpointenforce' + // are for the users to explicitly consent to enforce the checkpoints issued + // from checkpoint master. To enforce checkpoint, user needs to either issue + // command 'enforcecheckpoint true', or set configuration parameter + // checkpointenforce=1. The current enforcement setting can be queried via + // command 'getcheckpoint', where 'subscribemode' displays either 'enforce' + // or 'advisory'. The 'enforce' mode of subscribemode means checkpoints are + // enforced. The 'advisory' mode of subscribemode means checkpoints are not + // enforced but a warning message would be displayed if the node is on a + // different blockchain fork from the checkpoint, and this is the default mode. + // +Documentation. for checkpoints code.

[FAQ] What is a .m4 file?
m4 is a general-purpose macro processor included in all UNIX-like operating systems, and is a component of the POSIX standard.
The language was designed by Brian Kernighan and Dennis Ritchie for the original versions of UNIX. It is an extension of an earlier macro processor m3, written by Ritchie for the AP-3 minicomputer.[1]
The macro preprocessor operates as a text-replacement tool. It is employed to re-use text templates, typically in computer programming applications, but also in text editing and text-processing applications. Most users require m4 as a dependency of GNU autoconf.
