/**
 * @file
 * @brief Mozilla installation process
 *
 * Reads from stdin a list of instructions in the form:
 *
 * I:<base64 DER econded certificate>\r\n
 * R:<base64 DER econded certificate>\r\n
 * ...
 *
 * The maximum size of an input line is 9999 characters
 * (including the \r\n) at the end of the line.
 *
 * Certificates marked with I: will be installed and the ones
 * marked with R: will be searched and if available removed from
 * the databases.
 *
 * This tool tries to find all NSS databases the user has
 * access to and to execute the instructions on all of them.
 *
 * If there are other processes accessing the databases the caller
 * has to ensure that those are terminated before this process is
 * executed.
 *
 * Returns 0 on success (Even when no stores where found) an error value
 * as defined in errorcodes.h otherwise.
 *
 * Success messages are written to stdout. Errors to stderr. For logging
 * purposes each installation / removal of a certificate will be reported
 * with the profile name that it modified.
