You can update an existing BMC file. This may be necessary, for example, to add new messages or to change a message.
This can be done in the following way:
If the original SMC file for a given BMC file exists, you can edit it using a text editor. Otherwise, create a new SMC file.
Generate the new BMC file using the bmcgen command; place the new BMC file in the corresponding language directory.
In the directory containing the BMC file, run the bmcmap command to create a new BMC map file.
