       mvs - A command line Mediawiki client

	 mvs [Options] command [Options] [filename]

	 mvs -h|--help
	 mvs --version
	 mvs -D

	 mkdir wikistuff
	 cd wikistuff

	 mvs [-q|-v] login [-T]	[-d <wikihost>]	[-l language_code ] [-u	<username>] [-p	<password> ] [-w <wiki_path>]

	 mvs [-q|-v] update [<file> ..]

	 mvs [-q|-v] preview [-M] [-W] [-m "commit message"] <file>

       "mvs" is	a command line client whose purpose is to simplify offline
       editing of Wiki content.	 It allows you to get any number of pages from
       a given Mediawiki site, edit the	pages with any editor, get and merge
       any concurrent updates of the pages, and	then safely commit the users
       own changes back	to the version of the page on the server.

       The "mvs" commands which	take a filename	argument only accept a single
       filename	as so to avoid taking up too much server bandwidth.

       Note:Users of "mvs" from	before version 0.27 will notice	that in	this
       documentation the options are mostly listed after the "mvs" sub-
       command.	 This makes "mvs" behave more like "cvs", "svn", or "tla", and
       so should make it easier	for people who are used	to using those
       programs.  If you prefer	to use "mvs" the old way, that will still
       work, at	least for the next few versions.

   Step	1:  Create an account on the Mediawiki server.
       This should be done the normal way, by visiting the Mediawiki website
       to which	you want to contribute and creating a new account, setting the
       preferences, etc.

       It should hopefully go without saying that you will want	to become
       familiar	with the editorial, usage, and copyright guidelines of the
       site.  You should probably also make some contributions through the
       normal UI, and learn about following recent changes before contributing
       using mvs.

       In addition for the sake	of this	test you should	already	have a user
       page like User:<username> with something	on it, where <username>	is the
       user name with which you	established the	account.

   Step	2:  Create a working directory
       "mvs" works with	Mediawiki formatted files with a ".wiki" extension and
       which are stored	together with server information in a working
       directory.  You will have to have at least one working directory	for
       each Mediawiki site to which you	contribute.

       Simply use "mkdir" or the equivalent to make a new directory, and then
       before cd into that directory.

	 mkdir wikitravel.en
	 cd wikitravel.en

       All of the operations below should be done from this directory.

   Step	3:  Login using	"mvs login"
       To use login you	will need to know the hostname for the Mediawiki site
       to which	you want to contribute.

       Now use the host	with your username and password	to login.

	 mvs login -d -u <username> -p 'secret'

       If "mvs"	knows about your Mediawiki host	it will	set set	the
       "wiki_path" to the correct default for that server.  In this case it
       will also be able to select the language	version	of that	Wiki for you
       if you specify a	"language_code":

	 mvs login -d -l fr -u <username> -p	'secret'

       The code	must match the one which your wiki host	uses for a given
       language, and of	course the language version must exist for the given

       If your Mediawiki install uses a	nonstandard path to the	wiki script
       you can specify it on login.  The path to the wiki script is the	part
       of the URL after	the host name, and before the '?':

	 mvs login \
	   -d \
	   -u <username> \
	   -p 'secret' \
	   -w 'mw/wiki.phtml'

       You can change the edit and action paths	in the created .mediawiki file
       after successful	login accordingly.

       Now anything you	submit to the Mediawiki	server will be credited	to
       user "<username>".

       NOTE: If	you have been using an earlier version of "mvs"	you should
       probably	delete the .mediawiki file in your working directory.

   Step	4:  Use	"mvs update" to	fetch one or more working files
       You can fetch existing material off of the site,	or create new pages
       with "mvs update", remembering that your	files will need	a ".wiki"

	 mvs update User:<username>.wiki User:<username>/

       This should produce the output:

	 U User:<username>.wiki
	 A User:<username>/

       The U (for Updated) means that User:<username> was found	on the server
       and its contents	inserted into the local	files.	The A (for Added)
       means that the User:<username>/ page does not yet exist
       on the server, and will be added	when you run "mvs commit".

       Note that both of the pages we are working with are within your User
       Namespace.  It's	probably a good	idea to	restrict yourself to working
       with such pages while you are experimenting with	"mvs"

   Step	5:  Edit the files to make corrections and contributions
       Use your	favorite text editor to	edit the files.	 You might want	to
       check out this page to see if there is a	Mediawiki syntax highlighting
       file for	your editor:

       Of course if you	don't find a highlighting file for you editor you are
       welcome to create one and submit	it to the page above.

   Step	6:  Use	"mvs commit" to	submit your changes
       When you	are done editing a file	and would like to submit your changes
       to the wiki server use "mvs commit" to do so:

	 mvs commit -m 'commit message'	User:<username>.wiki

       Where 'commit message' is whatever you want to say about	the changes
       you are submitting and why.  You	must provide a commit message or "mvs
       commit" will fail.  You might also find that "mvs commit" fails
       complaining that	the file has changed on	the server.  If	this is	the
       case you	will need to use "mvs update" again to get the most recent

   Step	7: Update your wiki files
       You can use "mvs	update"	again at any time to reconcile any of your
       files with the most recent changes from the server.  Your changes will
       not be overwritten, but rather "mvs" will try to	merge any server
       changes into the	files as they exist in your working directory.	Note
       that update and commit only work	on one file at a time, as so to	help
       prevent accidents and server congestion.

       If for some reason there	is a conflict, i.e. you	and someone else have
       made changes which appear to be incompatible, and cannot	be resolved
       then your file will contain a conflict message, as detailed in the
       documentation for "mvs update" below.  You must resolve any conflicts
       before attempting to use	"mvs commit" on	the file.  This	is usually a
       very simple matter of choosing one version of the change	or another.
       You should use your best	judgement, consulting the relevant "Talk:"
       page to try to work out an agreement with the other contributor in
       cases where you just simply disagree.

       You can continue	editing	and committing changes with the	files in your
       working directory.  It might be a good idea for you to eventually
       create multiple working directories per site, perhaps grouping them by
       subject.	 This will work	fine with "mvs"	since it does not need to have
       a complete copy of all of the pages from	a given	server in a given
       working directory to work.

       All of your ".wiki" files should	be stored with UTF-8 encoding.	Upon
       login to	a given	server mvs will	determine the encoding used by that
       server, and will	upload in that encoding	only.  For servers using
       non-UTF-8 character sets	you should use HTML entities for any character
       you want	to represent which is outside of the server's character	set.
       This includes the english Wikipedia.  Most newer	Mediawiki sites
       however do use UTF-8, on	these sites HTML entities are never needed.

       The first argument after	the options should be one of the following two

       mvs login
	   Allows the user to login to the Mediawiki server using an existing
	   login and password for that server.	After calling "login" all
	   "commit"s from the same working directory will be logged as from
	   the logged-in user.

       mvs update
	   Updates the specified file[s] with content from the Mediawiki
	   server.  If a file does not exist it	is created and populated with
	   the current online version.	If there is no online version, the
	   file	either created and left	blank, or just left as it is.  If
	   there is content in both the	specified file and in the
	   corresponding Wiki page, an attempt is made to merge	the two, line
	   by line.  Files which are the same as the server version are

	   If no filenames are given on	the command line, all visible files
	   with	the .wiki extension are	processed.

	   Conflicting changes to a given line are detected on the basis of
	   the date of the most	recent update of the local file	and date of
	   the most recent change to the online	Wiki page.  If a line has
	   changed in both the online page and the local file it is flagged as
	   a conflict, as in CVS, but with a slightly different	syntax:

	     ********************Start of conflict 1  Insert to	Primary, Insert	to Secondary ************************************************************

	     The line as it appears on the server


	     The line as it appears locally
	     ********************End of	conflict 1********************************************************************************

	   "mvs	update"	reports	the status of files which it touches to	STDERR
	   with	a letter indicating the	file status, and then name of the
	   file, again like CVS.  The status letters are:

	   = (Unchanged)
	       The file	is the same as the page	on the server.

	   A (Added)
	       The file	will become a new page on the wiki server.

	   M (Modified)
	       The file	has been modified locally.

	   U (Updated)
	       The file	has been updated with changes from the wiki server.

	   C (Conflicts)
	       The file	contains conflict markers.

	   ? (Unknown)
	       Neither the file, nor a corresponding server page exist.

	   Commits any changes in the specified	local file to the Wiki site.
	   A check is made first to make sure that there are no	changes	on the
	   server more recent than the most recent update.  Nothing will be
	   comitted if the file	and server version are identical.

	   When	running	"mvs commit" you must use the "-m" flag	to send	a
	   commit message to the Mediawiki server.  e.g.:

	     mvs commit	-m 'Added Hotel	Eldorado'

	   This	command	functions identically to "mvs commit", except that
	   nothing is actually committed.  Instead, the	file is	uploaded and
	   the Mediawiki server	sends back a formatted preview.	 The "-m" flag
	   is optional.	 If you	set the	MVS_BROWSER environmental variable to
	   the path and	filename of your favorite browser, mvs will launch it
	   with	the preview page.

	   This	command	removes	any local version reference files relating to
	   pages you've	deleted.

	     mvs clean

   File	names
       Any additional arguments	are taken as local filenames to	be processed.
       The local filename of a given Mediawiki page will be the	same as	its
       URL encoded name	with the extension ".wiki".  If	no arguments are given
       then any	filenames with the "wiki" extension and	under the current
       directory are processed.

       Display usage information.

       Print information about known Mediawiki servers,	then exit.

       Causes the command to be	quiet.	Informational messages are suppressed.

   -u "<username>"
       Specifies a username for	"mvs login".

   -p "<password>"
       Specifies a password for	"mvs login".

   -l "<language_code>"
       The language code the wiki server uses to differentiate between
       language	versions.

   -m "<your message>"
       A commit	message	for "mvs commit".  Use this to explain the nature of
       your changes.

   -s "<your message>"
       Same as "-m"

   --minor <yes|no|default>
       Choose whether to mark change as	a minor	edit.  The default is to mark
       changes as minor	if the Mediawiki user profile is set to	do so by
       default.	 Use this when committing a change with	"mvs commit" or
       previewing with "mvs preview".

       Same as "--minor	yes".

   --watch <yes|no|keep|default>
       Choose whether to add the edited	page to	your watchlist.	 Specifying
       "keep" will maintain the	current	watched	status.	 The default is	to
       watch the page if it is already being watched, or if the	Mediawiki user
       profile is set to do so by default.  Use	this when committing a change
       with "mvs commit" or previewing with "mvs preview".

       Same as "--watch	yes".

   -w "<wiki path>"
       The path	on the given "host" to the Mediawiki script.  This defaults to
       wiki/wiki.phtml which is	correct	for a vanilla install of Mediawiki

       Verbose.	 If this is set	"mvs" will give	you lots of extra information
       about what it's doing.  The -q flag overrides this.

       The browser you prefer to use for previewing changes.

       A proxy server to use (if any), expressed as a standard URL, something
       like this:

	 export	HTTP_PROXY=http://[username:password@]

       This is an early	version	of this	program.  Future versions may have
       major differences which will effect your	ability	to use them
       interchangeably with this one.  In particular the initial "command"
       arguments may become options and	the handling of	conflicts might	change
