+# Unless you specify which option file to use (with the command line

+#
+# An options file can contain any long options which are available in
+# GnuPG. If the first non white space character of a line is a '#',
+# this line is ignored.  Empty lines are also ignored.
+#
+# See the man page for a list of options.

+# Uncomment the following option to get rid of the copyright notice

+#no-greeting
+
+# If you have more than 1 secret key in your keyring, you may want to
+# uncomment the following option and set your preferred keyid.
+
+#default-key 621CC013
+
+# If you do not pass a recipient to gpg, it will ask for one.  Using
+# this option you can encrypt to a default key.  Key validation will
+# not be done in this case.  The second form uses the default key as
+# default recipient.
+
+#default-recipient some-user-id
+#default-recipient-self
+
+# Use --encrypt-to to add the specified key as a recipient to all
+# messages.  This is useful, for example, when sending mail through a
+# mail client that does not automatically encrypt mail to your key.
+# In the example, this option allows you to read your local copy of
+# encrypted mail that you've sent to others.
+
+#encrypt-to some-key-id
+
+# By default GnuPG creates version 4 signatures for data files as
+# specified by OpenPGP.  Some earlier (PGP 6, PGP 7) versions of PGP
+# require the older version 3 signatures.  Setting this option forces
+# GnuPG to create version 3 signatures.
+
+#force-v3-sigs
+
+# Because some mailers change lines starting with "From " to ">From "
+# it is good to handle such lines in a special way when creating
+# cleartext signatures; all other PGP versions do it this way too.
+
+#no-escape-from-lines
+
+# If you do not use the Latin-1 (ISO-8859-1) charset, you should tell
+# GnuPG which is the native character set.  Please check the man page
+# for supported character sets.  This character set is only used for
+# metadata and not for the actual message which does not undergo any
+# translation.  Note that future version of GnuPG will change to UTF-8
+# as default character set.  In most cases this option is not required
+# as GnuPG is able to figure out the correct charset at runtime.
+
+#charset utf-8
+
+# Group names may be defined like this:
+#   group mynames = paige 0x12345678 joe patti
+#
+# Any time "mynames" is a recipient (-r or --recipient), it will be
+# expanded to the names "paige", "joe", and "patti", and the key ID
+# "0x12345678".  Note there is only one level of expansion - you
+# cannot make an group that points to another group.  Note also that
+# if there are spaces in the recipient name, this will appear as two
+# recipients.  In these cases it is better to use the key ID.

+
+# GnuPG can send and receive keys to and from a keyserver.  These
+# servers can be HKP, email, or LDAP (if GnuPG is built with LDAP
+# support).
+#
+# Example HKP keyserver:
+#      hkp://keys.gnupg.net
+#      hkp://subkeys.pgp.net
+#
+# Example email keyserver:
+#      mailto:[email protected]
+#
+# Example LDAP keyservers:
+#      ldap://keyserver.pgp.com
+#
+# Regular URL syntax applies, and you can set an alternate port
+# through the usual method:
+#      hkp://keyserver.example.net:22742
+#
+# Most users just set the name and type of their preferred keyserver.
+# Note that most servers (with the notable exception of
+# ldap://keyserver.pgp.com) synchronize changes with each other.  Note
+# also that a single server name may actually point to multiple
+# servers via DNS round-robin.  hkp://keys.gnupg.net is an example of
+# such a "server", which spreads the load over a number of physical
+# servers.  To see the IP address of the server actually used, you may use
+# the "--keyserver-options debug".
+
+keyserver hkp://keys.gnupg.net
+#keyserver mailto:[email protected]
+#keyserver ldap://keyserver.pgp.com
+
+# Common options for keyserver functions:
+#
+# include-disabled : when searching, include keys marked as "disabled"
+#                    on the keyserver (not all keyservers support this).
+#
+# no-include-revoked : when searching, do not include keys marked as
+#                      "revoked" on the keyserver.
+#
+# verbose : show more information as the keys are fetched.
+#           Can be used more than once to increase the amount
+#           of information shown.
+#
+# use-temp-files : use temporary files instead of a pipe to talk to the
+#                  keyserver.  Some platforms (Win32 for one) always
+#                  have this on.
+#
+# keep-temp-files : do not delete temporary files after using them
+#                   (really only useful for debugging)
+#
+# http-proxy="proxy" : set the proxy to use for HTTP and HKP keyservers.
+#                      This overrides the "http_proxy" environment variable,
+#                      if any.
+#
+# auto-key-retrieve : automatically fetch keys as needed from the keyserver
+#                     when verifying signatures or when importing keys that
+#                     have been revoked by a revocation key that is not
+#                     present on the keyring.
+#
+# no-include-attributes : do not include attribute IDs (aka "photo IDs")
+#                         when sending keys to the keyserver.
+
+#keyserver-options auto-key-retrieve
+
+# Display photo user IDs in key listings
+
+# list-options show-photos
+
+# Display photo user IDs when a signature from a key with a photo is
+# verified
+
+# verify-options show-photos
+
+# Use this program to display photo user IDs
+#
+# %i is expanded to a temporary file that contains the photo.
+# %I is the same as %i, but the file isn't deleted afterwards by GnuPG.
+# %k is expanded to the key ID of the key.
+# %K is expanded to the long OpenPGP key ID of the key.
+# %t is expanded to the extension of the image (e.g. "jpg").
+# %T is expanded to the MIME type of the image (e.g. "image/jpeg").
+# %f is expanded to the fingerprint of the key.
+# %% is %, of course.
+#
+# If %i or %I are not present, then the photo is supplied to the
+# viewer on standard input.  If your platform supports it, standard
+# input is the best way to do this as it avoids the time and effort in
+# generating and then cleaning up a secure temp file.
+#
+# If no photo-viewer is provided, GnuPG will look for xloadimage, eog,
+# or display (ImageMagick).  On Mac OS X and Windows, the default is
+# to use your regular JPEG image viewer.
+#
+# Some other viewers:
+# photo-viewer "qiv %i"
+# photo-viewer "ee %i"
+#
+# This one saves a copy of the photo ID in your home directory:
+# photo-viewer "cat > ~/photoid-for-key-%k.%t"
+#
+# Use your MIME handler to view photos:
+# photo-viewer "metamail -q -d -b -c %T -s 'KeyID 0x%k' -f GnuPG"
+
+# Passphrase agent
+#
+# We support the old experimental passphrase agent protocol as well as
+# the new Assuan based one (currently available in the "newpg" package
+# at ftp.gnupg.org/gcrypt/alpha/aegypten/).  To make use of the agent,
+# you have to run an agent as daemon and use the option
+#
+# use-agent
+# 
+# which tries to use the agent but will fallback to the regular mode
+# if there is a problem connecting to the agent.  The normal way to
+# locate the agent is by looking at the environment variable
+# GPG_AGENT_INFO which should have been set during gpg-agent startup.
+# In certain situations the use of this variable is not possible, thus
+# the option
+# 
+# --gpg-agent-info=<path>:<pid>:1
+#
+# may be used to override it.
+
+# Automatic key location
+#
+# GnuPG can automatically locate and retrieve keys as needed using the
+# auto-key-locate option.  This happens when encrypting to an email
+# address (in the "[email protected]" form), and there are no
+# [email protected] keys on the local keyring.  This option takes the
+# following arguments, in the order they are to be tried:
+# 
+# cert = locate a key using DNS CERT, as specified in RFC-4398.
+#        GnuPG can handle both the PGP (key) and IPGP (URL + fingerprint)
+#        CERT methods.
+#
+# pka = locate a key using DNS PKA.
+#
+# ldap = locate a key using the PGP Universal method of checking
+#        "ldap://keys.(thedomain)".  For example, encrypting to
+#        [email protected] will check ldap://keys.example.com.
+#
+# keyserver = locate a key using whatever keyserver is defined using
+#             the keyserver option.
+#
+# You may also list arbitrary keyservers here by URL.
+#
+# Try CERT, then PKA, then LDAP, then hkp://subkeys.net:
+#auto-key-locate cert pka ldap hkp://subkeys.pgp.net
