Cletus is a library to help with commmand line python programs.
It includes: - cletus_config: makes it easy for a program to combine config files, environmental variables, and arguments into a single schema-validated config. - cletus_supp: allows programs and users to “suppress” actions with a program simply by touching a file in a dedicated directory. The suppression action may be to quit, or to simply sleep or temporarily suspend processing. - cletus_log: just boilerplate for common logging. - cletus_job: a well-tested mechanism that uses a pid file to ensure that the same file doesn’t get run twice.
