10 /* @file Mozilla installation process
11 *
12 * Reads from stdin a list of instructions in the form:
13 *
14 * I:<base64 DER econded certificate>\r\n
15 * R:<base64 DER econded certificate>\r\n
16 * ...
17 *
18 * The maximum size of an input line is 1000 characters
19 * (including the \r\n) at the end of the line.
20 *
21 * Certificates marked with I: will be installed and the ones
22 * marked with R: will be searched and if available removed from
23 * the databases.
24 *
25 * This tool tries to find all NSS databases the user has
26 * access to and to execute the instructions on all of them.
27 *
28 * If there are other processes accessing the databases the caller
29 * has to ensure that those are terminated before this process is
30 * executed.
31 *
32 * Returns 0 on success (Even when no stores where found) an error value
33 * as defined in errorcodes.h otherwise.
34 *
35 * Success messages are written to stdout. Errors to stderr. For logging
36 * purposes each installation / removal of a certificate will be reported
37 * with the profile name that it modified.
