+@item --enable-dsa2
+@itemx --disable-dsa2
+Enables new-style DSA keys which (unlike the old style) may be larger
+than 1024 bit and use hashes other than SHA-1 and RIPEMD/160. Note
+that very few programs currently support these keys and signatures
+from them.
 
-@table @gnupgtabopt
+@item --photo-viewer @code{string}
+This is the command line that should be run to view a photo ID. "%i"
+will be expanded to a filename containing the photo. "%I" does the
+same, except the file will not be deleted once the viewer exits.
+Other flags are "%k" for the key ID, "%K" for the long key ID, "%f"
+for the key fingerprint, "%t" for the extension of the image type
+(e.g. "jpg"), "%T" for the MIME type of the image (e.g. "image/jpeg"),
+and "%%" for an actual percent sign. If neither %i or %I are present,
+then the photo will be supplied to the viewer on standard input.
 
-@item XXX
-foo
+The default viewer is "xloadimage -fork -quiet -title 'KeyID 0x%k'
+stdin". Note that if your image viewer program is not secure, then
+executing it from GnuPG does not make it secure.
 
+@item --exec-path @code{string}
+Sets a list of directories to search for photo viewers and keyserver
+helpers. If not provided, keyserver helpers use the compiled-in
+default directory, and photo viewers use the $PATH environment
+variable.
+Note, that on W32 system this value is ignored when searching for
+keyserver helpers.
 
-@item --armor
-@itemx -a
-@opindex armor
-Create ASCII armored output.  The default is to create the binary
-OpenPGP format.
+@item --keyring @code{file}
+Add @code{file} to the current list of keyrings. If @code{file} begins
+with a tilde and a slash, these are replaced by the $HOME
+directory. If the filename does not contain a slash, it is assumed to
+be in the GnuPG home directory ("~/.gnupg" if --homedir or $GNUPGHOME
+is not used).
 
-@item --output @var{file}
-@itemx -o @var{file}
-@opindex output
-Write output to @var{file}.
+Note that this adds a keyring to the current list. If the intent is
+to use the specified keyring alone, use --keyring along with
+--no-default-keyring.
 
-@item --max-output @code{n}
-@opindex max-output
-This option sets a limit on the number of bytes that will be generated
-when processing a file. Since OpenPGP supports various levels of
-compression, it is possible that the plaintext of a given message may be
-significantly larger than the original OpenPGP message. While GnuPG
-works properly with such messages, there is often a desire to set a
-maximum file size that will be generated before processing is forced to
-stop by the OS limits. Defaults to 0, which means "no limit".
+@item --secret-keyring @code{file}
+Same as --keyring but for the secret keyrings.
 
-@item --mangle-dos-filenames
-@itemx --no-mangle-dos-filenames
-@opindex mangle-dos-filenames
-@opindex no-mangle-dos-filenames
-Older version of Windows cannot handle filenames with more than one
-dot. --mangle-dos-filenames causes GnuPG to replace (rather than add to)
-the extension of an output filename to avoid this problem. This option
-is off by default and has no effect on non-Windows platforms.
+@item --primary-keyring @code{file}
+Designate @code{file} as the primary public keyring. This means that
+newly imported keys (via --import or keyserver --recv-from) will go to
+this keyring.
 
-@item --local-user @var{name}
-@itemx -u
-@opindex local-user
-Use @var{name} as the key to sign with. Note that this option overrides
---default-key.
+@item --trustdb-name @code{file}
+Use @code{file} instead of the default trustdb. If @code{file} begins
+with a tilde and a slash, these are replaced by the $HOME
+directory. If the filename does not contain a slash, it is assumed to
+be in the GnuPG home directory ("~/.gnupg" if --homedir or $GNUPGHOME
+is not used).
 
-@item --default-key @var{name}
-@opindex default-key
-Use @var{name} as the default key to sign with. If this option is not
-used, the default key is the first key found in the secret keyring.
-Note that -u or --local-user overrides this option.
+@include opt-homedir.texi
 
-@item --recipient @var{name}
-@itemx -r
-@opindex recipient
-Encrypt for user id @var{name}. If this option or --hidden-recipient is
-not specified, GnuPG asks for the user-id unless --default-recipient is
-given.
 
-@item --hidden-recipient @var{name}
-@itemx -R
-@opindex hidden-recipient
-Encrypt for user ID @var{name}, but hide the key ID of this user's
-key. This option helps to hide the receiver of the message and is a
-limited countermeasure against traffic analysis. If this option or
---recipient is not specified, GnuPG asks for the user ID unless
---default-recipient is given.
+@item --pcsc-driver @code{file}
+Use @code{file} to access the smartcard reader. The current default is
+`libpcsclite.so.1' for GLIBC based systems,
+`/System/Library/Frameworks/PCSC.framework/PCSC' for MAC OS X,
+`winscard.dll' for Windows and `libpcsclite.so' for other systems.
 
-@item --default-recipient @var{name}
-@opindex default-recipient
-Use @var{name} as default recipient if option --recipient is not used
-and don't ask if this is a valid one. @var{name} must be non-empty.
+@item --disable-ccid
+Disable the integrated support for CCID compliant readers. This
+allows to fall back to one of the other drivers even if the internal
+CCID driver can handle the reader. Note, that CCID support is only
+available if libusb was available at build time.
 
-@item --default-recipient-self
-@opindex default-recipient-self
-Use the default key as default recipient if option --recipient is not
-used and don't ask if this is a valid one. The default key is the first
-one from the secret keyring or the one set with --default-key.
+@item --reader-port @code{number_or_string}
+This option may be used to specify the port of the card terminal. A
+value of 0 refers to the first serial device; add 32768 to access USB
+devices. The default is 32768 (first USB device). PC/SC or CCID
+readers might need a string here; run the program in verbose mode to get
+a list of available readers. The default is then the first reader
+found.
 
-@item --no-default-recipient
-@opindex no-default-recipient
-Reset --default-recipient and --default-recipient-self.
+@item --display-charset @code{name}
+Set the name of the native character set. This is used to convert
+some informational strings like user IDs to the proper UTF-8 encoding.
+Note that this has nothing to do with the character set of data to be
+encrypted or signed; GnuPG does not recode user supplied data. If
+this option is not used, the default character set is determined from
+the current locale. A verbosity level of 3 shows the chosen set.
+Valid values for @code{name} are:
 
-@item --encrypt-to @code{name}
-Same as --recipient but this one is intended for use
-in the options file and may be used with
-your own user-id as an "encrypt-to-self". These keys
-are only used when there are other recipients given
-either by use of --recipient or by the asked user id.
-No trust checking is performed for these user ids and

+affect all following arguments. Both options may be used multiple
+times.
+
+@item --options @code{file}
+Read options from @code{file} and do not try to read
+them from the default options file in the homedir

-Treat input files as text and store them in the OpenPGP canonical text

+
+@item --max-cert-depth @code{n}
+Maximum depth of a certification chain (default is 5).
+
+@item --simple-sk-checksum
+Secret keys are integrity protected by using a SHA-1 checksum. This
+method is part of the upcoming enhanced OpenPGP specification but
+GnuPG already uses it as a countermeasure against certain attacks.
+Old applications don't understand this new format, so this option may
+be used to switch back to the old behaviour. Using this option bears
+a security risk. Note that using this option only takes effect when
+the secret key is encrypted - the simplest way to make this happen is
+to change the passphrase on the key (even changing it to the same
+value is acceptable).
+
+@item --no-sig-cache
+Do not cache the verification status of key signatures.
+Caching gives a much better performance in key listings. However, if
+you suspect that your public keyring is not save against write
+modifications, you can use this option to disable the caching. It
+probably does not make sense to disable it because all kind of damage
+can be done if someone else has write access to your public keyring.
+
+@item --no-sig-create-check
+GnuPG normally verifies each signature right after creation to protect
+against bugs and hardware malfunctions which could leak out bits from
+the secret key. This extra verification needs some time (about 115%
+for DSA keys), and so this option can be used to disable it.
+However, due to the fact that the signature creation needs manual
+interaction, this performance penalty does not matter in most settings.
+
+@item --auto-check-trustdb
+@itemx --no-auto-check-trustdb
+If GnuPG feels that its information about the Web of Trust has to be
+updated, it automatically runs the --check-trustdb command internally.
+This may be a time consuming process. --no-auto-check-trustdb
+disables this option.
+
+@item --use-agent
+@itemx --no-use-agent
+Try to use the GnuPG-Agent. Please note that this agent is still under
+development. With this option, GnuPG first tries to connect to the
+agent before it asks for a passphrase. --no-use-agent disables this
+option.
+
+@item --gpg-agent-info
+Override the value of the environment variable
+@samp{GPG_AGENT_INFO}. This is only used when --use-agent has been given
+
+@item --lock-once
+Lock the databases the first time a lock is requested
+and do not release the lock until the process
+terminates.
+
+@item --lock-multiple
+Release the locks every time a lock is no longer
+needed. Use this to override a previous --lock-once
+from a config file.
+
+@item --lock-never
+Disable locking entirely. This option should be used only in very
+special environments, where it can be assured that only one process
+is accessing those files. A bootable floppy with a stand-alone
+encryption system will probably use this. Improper usage of this
+option may lead to data and key corruption.
+
+@item --exit-on-status-write-error
+This option will cause write errors on the status FD to immediately
+terminate the process. That should in fact be the default but it
+never worked this way and thus we need an option to enable this, so
+that the change won't break applications which close their end of a
+status fd connected pipe too early. Using this option along with
+--enable-progress-filter may be used to cleanly cancel long running
+gpg operations.
+
+@item --limit-card-insert-tries @code{n}
+With @code{n} greater than 0 the number of prompts asking to insert a
+smartcard gets limited to N-1. Thus with a value of 1 gpg won't at
+all ask to insert a card if none has been inserted at startup. This
+option is useful in the configuration file in case an application does
+not know about the smartcard support and waits ad infinitum for an
+inserted card.
+
+@item --no-random-seed-file
+GnuPG uses a file to store its internal random pool over invocations.
+This makes random generation faster; however sometimes write operations
+are not desired. This option can be used to achieve that with the cost of
+slower random generation.
+
+@item --no-greeting
+Suppress the initial copyright message.
+
+@item --no-secmem-warning
+Suppress the warning about "using insecure memory".
+
+@item --no-permission-warning
+Suppress the warning about unsafe file and home directory (--homedir)
+permissions. Note that the permission checks that GnuPG performs are
+not intended to be authoritative, but rather they simply warn about
+certain common permission problems. Do not assume that the lack of a
+warning means that your system is secure.
+
+Note that the warning for unsafe --homedir permissions cannot be
+suppressed in the gpg.conf file, as this would allow an attacker to
+place an unsafe gpg.conf file in place, and use this file to suppress
+warnings about itself. The --homedir permissions warning may only be
+suppressed on the command line.
+
+@item --no-mdc-warning
+Suppress the warning about missing MDC integrity protection.
+
+@item --require-secmem
+@itemx --no-require-secmem
+Refuse to run if GnuPG cannot get secure memory. Defaults to no
+(i.e. run, but give a warning).
+
+
+@item --require-cross-certification
+@itemx --no-require-cross-certification
+When verifying a signature made from a subkey, ensure that the cross
+certification "back signature" on the subkey is present and valid.
+This protects against a subtle attack against subkeys that can sign.
+Defaults to --require-cross-certification for @command{gpg2}.
+
+@item --expert
+@itemx --no-expert
+Allow the user to do certain nonsensical or "silly" things like
+signing an expired or revoked key, or certain potentially incompatible
+things like generating unusual key types. This also disables certain

+@itemx -r
+@opindex recipient
+Encrypt for user id @var{name}. If this option or --hidden-recipient is
+not specified, GnuPG asks for the user-id unless --default-recipient is
+given.
+
+@item --hidden-recipient @var{name}
+@itemx -R
+@opindex hidden-recipient
+Encrypt for user ID @var{name}, but hide the key ID of this user's
+key. This option helps to hide the receiver of the message and is a
+limited countermeasure against traffic analysis. If this option or
+--recipient is not specified, GnuPG asks for the user ID unless
+--default-recipient is given.
+
+@item --encrypt-to @code{name}
+Same as --recipient but this one is intended for use
+in the options file and may be used with
+your own user-id as an "encrypt-to-self". These keys
+are only used when there are other recipients given
+either by use of --recipient or by the asked user id.
+No trust checking is performed for these user ids and
+even disabled keys can be used.

+@item --hidden-encrypt-to @code{name}
+Same as --hidden-recipient but this one is intended for use in the
+options file and may be used with your own user-id as a hidden

+
+@item --no-encrypt-to
+Disable the use of all --encrypt-to and --hidden-encrypt-to keys.
+
+@item --group @code{name=value1 }
+Sets up a named group, which is similar to aliases in email programs.
+Any time the group name is a recipient (-r or --recipient), it will be
+expanded to the values specified. Multiple groups with the same name
+are automatically merged into a single group.
+
+The values are @code{key IDs} or fingerprints, but any key description
+is accepted. Note that a value with spaces in it will be treated as
+two different values. Note also there is only one level of expansion
+- you cannot make an group that points to another group. When used
+from the command line, it may be necessary to quote the argument to
+this option to prevent the shell from treating it as multiple
+arguments.
+
+@item --ungroup @code{name}
+Remove a given entry from the --group list.
+
+@item --no-groups
+Remove all entries from the --group list.
+
+@item --local-user @var{name}
+@itemx -u
+@opindex local-user
+Use @var{name} as the key to sign with. Note that this option overrides
+--default-key.
+
+@item --try-all-secrets
+Don't look at the key ID as stored in the message but try all secret
+keys in turn to find the right decryption key. This option forces the

+@item -t, --textmode
+@itemx --no-textmode
+Treat input files as text and store them in the OpenPGP canonical text
+form with standard "CRLF" line endings. This also sets the necessary

+two platforms that have different line ending conventions (UNIX-like
+to Mac, Mac to Windows, etc). --no-textmode disables this option, and
+is the default.
 
-@item show-sig-subpackets
-Include signature subpackets in the key listing. This option can take
-an optional argument list of the subpackets to list. If no argument

+OpenPGP states that an implementation should generate v4 signatures
+but PGP versions 5 through 7 only recognize v4 signatures on key

+@item --force-v4-certs
+@itemx --no-force-v4-certs
+Always use v4 key signatures even on v3 keys. This option also
+changes the default hash algorithm for v3 RSA keys from MD5 to SHA-1.
+--no-force-v4-certs disables this option.
 
-@item show-keyserver-urls
-Show any preferred keyserver URL in the signature being verified.
-Defaults to no.
+@item --force-mdc
+Force the use of encryption with a modification detection code. This
+is always used with the newer ciphers (those with a blocksize greater
+than 64 bits), or if all of the recipient keys indicate MDC support in
+their feature flags.
 
-@item show-uid-validity
-Display the calculated validity of the user IDs on the key that issued
-the signature. Defaults to no.
+@item --disable-mdc
+Disable the use of the modification detection code. Note that by
+using this option, the encrypted message becomes vulnerable to a

-@item show-unusable-uids
-Show revoked and expired user IDs during signature verification.
-Defaults to no.
+@item --personal-cipher-preferences @code{string}
+Set the list of personal cipher preferences to @code{string}, this list
+should be a string similar to the one printed by the command "pref" in
+the edit menu. This allows the user to factor in their own preferred
+algorithms when algorithms are chosen via recipient key preferences.
+The most highly ranked cipher in this list is also used for the

-@item --photo-viewer @code{string}
-This is the command line that should be run to view a photo ID. "%i"
-will be expanded to a filename containing the photo. "%I" does the
-same, except the file will not be deleted once the viewer exits.
-Other flags are "%k" for the key ID, "%K" for the long key ID, "%f"
-for the key fingerprint, "%t" for the extension of the image type
-(e.g. "jpg"), "%T" for the MIME type of the image (e.g. "image/jpeg"),
-and "%%" for an actual percent sign. If neither %i or %I are present,
-then the photo will be supplied to the viewer on standard input.
+@item --s2k-cipher-algo @code{name}
+Use @code{name} as the cipher algorithm used to protect secret keys.
+The default cipher is CAST5. This cipher is also used for
+conventional encryption if --personal-cipher-preferences and
+--cipher-algo is not given.
 
-The default viewer is "xloadimage -fork -quiet -title 'KeyID 0x%k'

+The default algorithm is SHA-1.
 
-@item --exec-path @code{string}
-Sets a list of directories to search for photo viewers and keyserver
-helpers. If not provided, keyserver helpers use the compiled-in
-default directory, and photo viewers use the $PATH environment
-variable.
-Note, that on W32 system this value is ignored when searching for
-keyserver helpers.
+@item --s2k-mode @code{n}
+Selects how passphrases are mangled. If @code{n} is 0 a plain
+passphrase (which is not recommended) will be used, a 1 adds a salt to
+the passphrase and a 3 (the default) iterates the whole process a
+couple of times. Unless --rfc1991 is used, this mode is also used for
