aheinecke@99:  * Certificates marked with I: will be installed and the ones
aheinecke@99:  * marked with R: will be searched and if available removed from
aheinecke@99:  * the databases.
aheinecke@99:  *
aheinecke@99:  * This tool tries to find all NSS databases the user has
aheinecke@99:  * access to and to execute the instructions on all of them.
aheinecke@99:  *
aheinecke@99:  * If there are other processes accessing the databases the caller
aheinecke@99:  * has to ensure that those are terminated before this process is
aheinecke@99:  * executed.
aheinecke@99:  *
aheinecke@238:  * If the same certificate is marked to be installed and to be removed
aheinecke@238:  * in one call the behavior is undefined. This should be avoided and
aheinecke@238:  * may lead to errors.
aheinecke@238:  *
aheinecke@99:  * Returns 0 on success (Even when no stores where found) an error value
aheinecke@99:  * as defined in errorcodes.h otherwise.
aheinecke@99:  *
aheinecke@99:  * Success messages are written to stdout. Errors to stderr. For logging
aheinecke@99:  * purposes each installation / removal of a certificate will be reported
