CAM v0.1 - (c)2006 by <ale@incal.net> 
A Certification Authority manager for complex situations.
Usage: %s <COMMAND> [<ARG>...]
Known commands:

  init
    Initialize the environment by creating the necessary
    directory structure

  newca [<RSA_CRT> [<DSA_CRT>]]
    Create a new CA certificate (otherwise you can import
    your own certificates)

  gen <TAG>...
    Create (or re-create) the certificates corresponding
    to TAG

  list
    List all known certificates

  files <TAG>...
    Dump all the certificate-related files of this TAG

  check
    Should be run weekly from a cron job to warn you if
    some certificates are about to expire (controlled by
    the 'warning_days' parameter in the 'global' section
    of the configuration)


The configuration will be read from '%s'.
It consists of a ini-style file, with one 'ca' section that
specifies global CA parameters, and more sections for each
tag with certificate-specific information. See the examples
for more details on how to write your own configuration.
