The SecCompany setup team for Trusted Extensions makes a printed copy and an online copy of the installed label_encodings file. The copy is used in case of problems with the new version of the file that the security administrator supplies.
The security administrator uses a text editor to create the label_encodings file and then uses the chk_encodings -a command to check the file. After the file passes all semantic and syntactic checks, the security administrator backs up the current version of the label_encodings file, and installs the new label_encodings file.
