+Firma CHANGELOG 
+---------------
+
+05/05/2005 - 0.3-cvs - luis
+
+  - New functions: list_admin, choose_uid and version.
+  - Renamed functions
+      GPGSTDERR -> get_gpg_stderr
+      SUBSCRIBERS -> get_subscribers_list
+      get_headers -> get_message_headers
+  - New args:
+    -h: chama a usage()
+    -v: chama a version()
+  - Option -a passes STDIN line by line to list_admin
+  - Added some checkings in the main procedure 
+  - Some minor syntax changes
+
+02/08/2005 - 0.3-cvs - rhatto
+
+  - Completed function newlist (still needs tests)
+  - New function: gpg_args
+
+25/05/2005 - v0.2.x - rhatto
+
+  - Message is now stored in two arrays, MESSAGE and GPG_MESSAGE.
+    Temporary files are no longer needed. Deleted TMP var.
+  - Adapted firma to work with these two arrays. Lots of changes along
+    the code.
+  - Reorganized the code again, splitting part of the process_message
+    function into three new functions (get_message, get_gpg_message
+    and get_headers).
+  - new functions: get_message, get_gpg_message, get_headers,
+  - added export LANG=en_US 
+
+14/05/2005 - v0.2.3 - rhatto
+
+  - Changed project description.
+  - Two new variables: VERSION and CONFIG. The later stores the path
+    to the configuration file.
+  - Reorganized the code, splitting it into two functions
+    (check_config and process_message).
+  - An exit code of 1 is now given if an error occurs.
+  - Implemented a simple command line syntax: firma now has to be
+    called along with an option (e.g., -p to process a message),
+    followed by the path to the configuration file to be used.
+  - Created a new function (usage), which displays firma's usage if
+    its called without a command line option.
+  - Rearranged some comments along the code.
+  - New functions are: check_config, eval_config, usage, process_message and
+    splited the code into these routines
+
+12/05/2005 - v0.2.2 - luis
+
+  major code cleanup and bug fix release
+
+  - New: Implemented size and complexity checks for the lists' passphrase.
+  - firma would not work as expected if the PASSWD variable contained
+    characters such as $, `, ', ", \. Fixed. Now PASSWD has to be^M
+    enclosed in single quotes and cannot contain any single quote in
+    its value.
+  - Checked the entire code and tried to make it clearer and more
+    consistent. Lots of small changes and minor fixes.
+  - BASH was looking for the configuration file first on its PATH and
+    only then on the current directory. Disabled sourcepath to avoid
+    this behavior.
+  - A From header containing more than one "<" would turn the variable
+    FROMADD useless. Fixed.
+  - When a message's signature is found invalid, the notification
+    about it is now sent separately for the sender and the list
+    administrators.
+  - Other minor fixes and improvements.
+  - fix LISTNAME and LISTADMIN case sensitiveness
+
+18/04/2005 - v0.2.1 - luis
+
+  - Added some simple checks for the values entered in the
+    configuration file. If any of these checks fail, firma exits and
+    shows what should be corrected in the file.
+
+  - GPGLIST now lists public keys using the gpg option
+    "--with-colons". Definitely much easier to parse.
+
+  - added --no-permission-warning on $GPGCOMMAND.
+
+  - first tests with --hidden-recipient, but not added
+
+  - Fixed the FROMADD variable. It wasn't working on the last version
+
+    - FROMADD=$(echo $FROMADD \
+        | if grep -q "<" ; \
+          then echo $FROMADD | grep -o "<.*>" | sed -e "s/[<>]//g" ; \
+          else echo $FROMADD ; \
+          fi)
+
+    + FROMADD=$(echo $FROM \
+        | if grep -q "<" ; \
+          then echo $FROM | grep -o "<.*>" | sed -e "s/[<>]//g" ; \
+          else echo $FROM ; \
+          fi)
+
+  - created routines to check config file vars
+
+  - changed SUBJECT to SUBJECT=$(grep -m 1 "^Subject:" $TMP | cut -d : -f 2- | sed "s/^ //")
+
+  - changed FROM to FROM=$(grep -m 1 "^From:" $TMP | cut -f 2 -d :)
+
+17/04/2005 - v0.2 - luis
+
+  - Lists can now have a passphrase. Added option "--passphrase-fd 0"
+    to the GPGDECRYPT and GPGENCRYPT variables.
+  - Added a new variable to the configuration file: LISTADMIN. It
+    should contain the email address of one or more list
+    administrator(s).
+  - Added signature checking for received messages. If the signature
+    is found valid, the message is sent to the list. If its invalid,
+    its returned to the sender and to the list administrator(s). If
+    the message was not encrypted and/or signed, a note is returned
+    to the sender.
+  - Added a few options to the GPGCOMMAND variable: "--batch",
+    "--no-tty", "--no-use-agent" and "--no-permission-warning".
+
+    GPGCOMMAND="$GPG \
+        --quiet \     
+        --homedir $GPGDIR \
+        --batch \
+        --no-tty \
+        --no-use-agent"
+
+  - Added two new functions: GPGSTDERR and SUBSCRIBERS. The first gets
+    gpg STDERR and discards its STDOUT and the later returns the
+    subscribers list.
+
+    function GPGSTDERR {
+       echo "$PASSWD" \
+       | ($GPGDECRYPT --status-fd 2 $TMP.gpg 1> /dev/null) 2>&1 ;
+    }
+
+    function SUBSCRIBERS {
+       $GPGLIST \
+       | sed -n '/$LISTNAME/d;/pub/p' \
+       | grep -o '<.*>' \
+       | sed -e 's/[<>]//g' ;
+    }
+
+  - Added a new variable, FROMADD, which contains the sender's email
+    address.
+
+    FROMADD=$(echo $FROMADD \
+       | if grep -q '<' ; \
+       then echo $FROMADD | grep -o '<.*>' | sed -e 's/[<>]//g' ; \
+       else echo $FROMADD ; \
+       fi)
+
+   TODO: find a better place to this var.
+
+Feb 2005 - v0.1 - rhatto
+
+  - First public release and proof of concept
+  - Based on pgplist (http://www.rediris.es/app/pgplist/index.en.html),
+    but completely written from scratch
+  - Strips all mail headers
+  - Use keyring as database
+  - List variables are sourced from a configuration file.
+  - List subscription is managed through gpg public keyrings, one
+    keyring for each mailing list.
+  - Message is read from STDIN, passed to it by postfix or some
+    other MTA.
+  - Encrypted message is saved in a temporary file on disk. The
+    decrypted message though is not stored in disk, but passed to
+    the MTA through a pipe.
+  - Message is then decrypted, re-encrypted and sent separately to
+    each list subscriber.
