initial transition from gpm to secstore The name 'gpm' has several problems: - There already *is* a Linux program called 'gpm' - The utility is now much more general, and no longer forces you to use gpg - Although the primary use is still passwords, it can handle multi-line and binary files, so the 'pm' part is not very correct either The utility has been renamed to 'secstore', and some transition (env variable names, invocation changes, etc.) has been made. This version is *not* compatible with any versions of gpm, and never will be.
