\1s\0etdefs	  \2name\0 - set \2name\0 as the default key for signing and decrypting
\1k\0eygen	  \2name\0 - create a new pair of PPSEKS (protected private secret encryption key string)
						 
						 Use the  to sign and decrypt.
						 with SEKS (U Shared Encryption Key String)

\1l\0ist	  \2term\0 - print public SEKS keys in the \$SEKSZONE\0 matching \2term\0

\1DisplayPP\0 \2name\0 - detailed information for protected private SEKS key \2name\0
\1DumpPPCatalog\0      - dump all protected \1private\0 SEKS keys cataloged from the \$SEKSZONE\0

The first letter of any command can be used as a shortcut. For example, \1e\0 is the same as \1encrypt\0.
Except the DisplayPP DumpPPCatalog, as they output protected private SEKS key information.  

By default {{ argv }} reads from stdin and writes to stdout. Using a pipe is 
recommended for large files. However, \1-i\0 and \1-o\0 can be used to specify input
and output files. This will overwrite the output file without warning.

By default, {{ argv }} will use \4~/.sekszone\0 for configuration and key storage. This
can be changed by setting the environment variable \$SEKSZONE\0 to an empty directory or 
existing SEKS ZONE . The permissions of this directory can be whatever you like,
but it is a good idea to ensure that only your user can access the SEKS ZONE.

\$PPSEKS\0 can be used to specify a protected private secret encryption key string
to use instead of the default PPSEKS.

\$PPSEKS\0 can change the default key for signing and decrypting.

Use {{ argv }} help for more usage information.
