Initial revision in this repository.
Merged in changes from development repository:

   Added code for handling the `--gpg-passphrase' option.  This is somewhat complicated, because
   the memory, in which it's stored must be locked into main memory, i.e., not swapped out to the
   file system.  In addition, the passphrase should not appear in the command-line, in order to
   prevent it from being read from `/proc/[Process ID]/cmdline'.  However, shell commands in
   Makefiles behave differently from ones called directly from the shell, and in order to get this to
   work, I had to put the code into a shellscript, which I call from `Makefile.am'.

Commented-out the input command for `cmdlnopt.web'.  Added "TODO" note to myself to
add another driver file for cweave.
Updated generated files.
