/*
** COMMAND: settings

**                     external diff programs.  If FALSE, skip these files.
**
**    diff-command     External command to run when performing a diff.
**                     If undefined, the internal text diff will be used.
**
**    dont-push        Prevent this repository from pushing from client to
**                     server.  Useful when setting up a private branch.
**
**    editor           Text editor command used for check-in comments.
**
**    empty-dirs       A comma or newline-separated list of pathnames. On
**     (versionable)   update and checkout commands, if no file or directory
**                     exists with that name, an empty directory will be
**                     created.
**
**    encoding-glob    The VALUE is a comma or newline-separated list of GLOB
**     (versionable)   patterns specifying files that the "commit" command will
**                     ignore when issuing warnings about text files that may
**                     use another encoding than ASCII or UTF-8. Set to "*"
**                     to disable encoding checking.
**
**    gdiff-command    External command to run when performing a graphical
**                     diff. If undefined, text diff will be used.
**
**    gmerge-command   A graphical merge conflict resolver command operating
**                     on four files.
**                     Ex: kdiff3 "%baseline" "%original" "%merge" -o "%output"

**                     Disable on large repositories for a performance
**                     improvement.
**
**    self-register    Allow users to register themselves through the HTTP UI.
**                     This is useful if you want to see other names than
**                     "Anonymous" in e.g. ticketing system. On the other hand
**                     users can not be deleted. Default: off.
**
**    ssh-command      Command used to talk to a remote machine with
**                     the "ssh://" protocol.
**
**    ssl-ca-location  The full pathname to a file containing PEM encoded
**                     CA root certificates, or a directory of certificates
**                     with filenames formed from the certificate hashes as
**                     required by OpenSSL.
**                     If set, this will override the OS default list of
**                     OpenSSL CAs. If unset, the default list will be used.
**                     Some platforms may add additional certificates.
**                     Check your platform behaviour is as required if the
**                     exact contents of the CA root is critical for your
**                     application.
**
**    ssl-identity     The full pathname to a file containing a certificate
**                     and private key in PEM format. Create by concatenating
**                     the certificate and private key files.
**                     This identity will be presented to SSL servers to
**                     authenticate this client, in addition to the normal
**                     password authentication.
**



**    tcl              If enabled (and Fossil was compiled with Tcl support),
**                     Tcl integration commands will be added to the TH1
**                     interpreter, allowing arbitrary Tcl expressions and
**                     scripts to be evaluated from TH1.  Additionally, the Tcl
**                     interpreter will be able to evaluate arbitrary TH1
**                     expressions and scripts. Default: off.
**
**    tcl-setup        This is the setup script to be evaluated after creating
**                     and initializing the Tcl interpreter.  By default, this
**                     is empty and no extra setup is performed.
**
**    th1-setup        This is the setup script to be evaluated after creating
**                     and initializing the TH1 interpreter.  By default, this
**                     is empty and no extra setup is performed.
**





**    web-browser      A shell command used to launch your preferred
**                     web browser when given a URL as an argument.
**                     Defaults to "start" on windows, "open" on Mac,
**                     and "firefox" on Unix.
**
** Options:
**   --global   set or unset the given property globally instead of

**
** The --recompute flag causes the content of the "leaf" table in the
** repository database to be recomputed.
**
** Options:
**   --all        show ALL leaves
**   --closed     show only closed leaves
**   --bybranch   order output by branch name
**   --recompute  recompute the "leaf" table in the repository DB

** COMMAND: merge
**
** Usage: %fossil merge ?OPTIONS? ?VERSION?
**
** The argument VERSION is a version that should be merged into the
** current checkout.  All changes from VERSION back to the nearest
** common ancestor are merged.  Except, if either of the --cherrypick or
** --backout options are used only the changes associated with the
** single check-in VERSION are merged.  The --backout option causes
** the changes associated with VERSION to be removed from the current
** checkout rather than added.
**
** If the VERSION argument is omitted, then Fossil attempts to find
** a recent fork on the current branch to merge.
**
** Only file content is merged.  The result continues to use the
** file and directory names from the current checkout even if those
** names might have been changed in the branch being merged in.
**
** Other options:

<h1>Up and running in 5 minutes as a single user</h1>
<p>This short document explains the main basic Fossil commands for a single 
user, ie. with no additional users, with no need to synchronize with some remote 
repository, and no need for branching/forking.</p>

<h2>Create a new repository</h2>
<p>fossil new c:\test.repo</p>
<p>This will create the new SQLite binary file that holds the repository, ie. 
files, tickets, wiki, etc. It can be located anywhere, although it's considered 
best practise to keep it outside the work directory where you will work on files 
after they've been checked out of the repository.</p>

<h2>Open the repository</h2>
<p>cd c:\temp\test.fossil</p>
<p>fossil open c:\test.repo</p>
<p>This will check out the last revision of all the files in the repository, 
if any, into the current work directory. In addition, it will create a binary 
file _FOSSIL_ to keep track of changes (on non-Windows systems it is called
<tt>.fslckout</tt>).</p>

<h2>Add new files</h2>
<p>fossil add .</p>
<p>To tell Fossil to add new files to the repository. The files aren't actually 
added until you run &quot;commit&quot;. When using &quot;.&quot;, it tells Fossil 
to add all the files in the current directory recursively, ie. including all 
the files in all the subdirectories.</p>
<p>Note: To tell Fossil to ignore some extensions:</p>
<p>fossil settings ignore-glob &quot;*.o,*.obj,*.exe&quot; --global</p>

<h2>Remove files that haven't been commited yet</h2>
<p>fossil delete myfile.c</p>
<p>This will simply remove the item from the list of files that were previously 
added through &quot;fossil add&quot;.</p>

<h2>Check current status</h2>
<p>fossil changes</p>
<p>This shows the list of changes that have been done and will be commited the 
next time you run &quot;fossil commit&quot;. It's a useful command to run before 
running &quot;fossil commit&quot; just to check that things are OK before proceeding.</p>

<h2>Commit changes</h2>
<p>To actually apply the pending changes to the repository, eg. new files marked 
for addition, checked-out files that have been edited and must be checked-in, 
etc.</p>

<p>fossil commit -m "Added stuff"</p>

If no file names are provided on the command-line then all changes will be checked in,
otherwise just the listed file(s) will be checked in.

<h2>Compare two revisions of a file</h2>
<p>If you wish to compare the last revision of a file and its checked out version 
in your work directory:</p>
<p>fossil gdiff myfile.c</p>
<p>If you wish to compare two different revisions of a file in the repository:</p>
<p>fossil finfo myfile: Note the first hash, which is the UUID of the commit 
when the file was commited</p>
<p>fossil gdiff --from UUID#1 --to UUID#2 myfile.c</p>
<h2>Cancel changes and go back to previous revision</h2>
<p>fossil revert myfile.c</p>
<p>Fossil does not prompt when reverting a file. It simply reminds the user about the
"undo" command, just in case the revert was a mistake.</p>


<h2>Close the repository</h2>
<p>fossil close</p>
<p>This will simply remove the _FOSSIL_ at the root of the work directory but 
will not delete the files in the work directory. From then on, any use of &quot;fossil&quot; 
will trigger an error since there is no longer any connection.</p>
