+" Section: Documentation {{{1
+"
+" Provides functions to invoke various source control commands on the current
+" file (either the current buffer, or, in the case of an directory buffer, the
+" directory and all subdirectories associated with the current buffer). The
+" output of the commands is captured in a new scratch window.
+"
+" This plugin needs additional extension plugins, each specific to a source
+" control system, to function. Those plugins should be placed in a
+" subdirectory of the standard plugin directory named 'vcscommand'. Several
+" options include the name of the version control system in the option name.
+" Such options use the placeholder text '{VCSType}', which would be replaced
+" in actual usage with 'CVS' or 'SVN', for instance.
+"
+" Command documentation {{{2
+"
+" VCSAdd Adds the current file to source control.
+"
+" VCSAnnotate Displays the current file with each line annotated with the
+" version in which it was most recently changed. If an
+" argument is given, the argument is used as a revision
+" number to display. If not given an argument, it uses the
+" most recent version of the file on the current branch.
+" Additionally, if the current buffer is a VCSAnnotate buffer
+" already, the version number on the current line is used.
+"
+" VCSBlame Alias for 'VCSAnnotate'.
+"
+" VCSCommit[!] Commits changes to the current file to source control.
+"
+" If called with arguments, the arguments are the log message.
+"
+" If '!' is used, an empty log message is committed.
+"
+" If called with no arguments, this is a two-step command.
+" The first step opens a buffer to accept a log message.
+" When that buffer is written, it is automatically closed and
+" the file is committed using the information from that log
+" message. The commit can be abandoned if the log message
+" buffer is deleted or wiped before being written.
+"
+" VCSDelete Deletes the current file and removes it from source control.
+"
+" VCSDiff With no arguments, this displays the differences between
+" the current file and its parent version under source
+" control in a new scratch buffer.
+"
+" With one argument, the diff is performed on the
+" current file against the specified revision.
+"
+" With two arguments, the diff is performed between the
+" specified revisions of the current file.
+"
+" This command uses the 'VCSCommand{VCSType}DiffOpt' variable
+" to specify diff options. If that variable does not exist,
+" a plugin-specific default is used. If you wish to have no
+" options, then set it to the empty string.
+"
+" VCSGotoOriginal Jumps to the source buffer if the current buffer is a VCS
+" scratch buffer. If VCSGotoOriginal[!] is used, remove all
+" VCS scratch buffers associated with the original file.
+"
+" VCSInfo Displays extended information about the current file in a
+" new scratch buffer.
+"
+" VCSLock Locks the current file in order to prevent other users from
+" concurrently modifying it. The exact semantics of this
+" command depend on the underlying VCS.
+"
+" VCSLog Displays the version history of the current file in a new
+" scratch buffer.
+"
+" VCSRemove Alias for 'VCSDelete'.
+"
+" VCSRevert Replaces the modified version of the current file with the
+" most recent version from the repository.
+"
+" VCSReview Displays a particular version of the current file in a new
+" scratch buffer. If no argument is given, the most recent
+" version of the file on the current branch is retrieved.
+"
+" VCSStatus Displays versioning information about the current file in a
+" new scratch buffer.
+"
+" VCSUnlock Unlocks the current file in order to allow other users from
+" concurrently modifying it. The exact semantics of this
+" command depend on the underlying VCS.
+"
+" VCSUpdate Updates the current file with any relevant changes from the
+" repository.
+"
+" VCSVimDiff Uses vimdiff to display differences between versions of the
+" current file.
+"
+" If no revision is specified, the most recent version of the
+" file on the current branch is used. With one argument,
+" that argument is used as the revision as above. With two
+" arguments, the differences between the two revisions is
+" displayed using vimdiff.
+"
+" With either zero or one argument, the original buffer is
+" used to perform the vimdiff. When the scratch buffer is
+" closed, the original buffer will be returned to normal
+" mode.
+"
+" Once vimdiff mode is started using the above methods,
+" additional vimdiff buffers may be added by passing a single
+" version argument to the command. There may be up to 4
+" vimdiff buffers total.
+"
+" Using the 2-argument form of the command resets the vimdiff
+" to only those 2 versions. Additionally, invoking the
+" command on a different file will close the previous vimdiff
+" buffers.
+"
+" Mapping documentation: {{{2
+"
+" By default, a mapping is defined for each command. User-provided mappings
+" can be used instead by mapping to <Plug>CommandName, for instance:
+"
+" nmap ,ca <Plug>VCSAdd
+"
+" The default mappings are as follow:
+"
+" <Leader>ca VCSAdd
+" <Leader>cn VCSAnnotate
+" <Leader>cc VCSCommit
+" <Leader>cD VCSDelete
+" <Leader>cd VCSDiff
+" <Leader>cg VCSGotoOriginal
+" <Leader>cG VCSGotoOriginal!
+" <Leader>ci VCSInfo
+" <Leader>cl VCSLog
+" <Leader>cL VCSLock
+" <Leader>cr VCSReview
+" <Leader>cs VCSStatus
+" <Leader>cu VCSUpdate
+" <Leader>cU VCSUnlock
+" <Leader>cv VCSVimDiff
+"
+" Options documentation: {{{2
+"
+" Several variables are checked by the script to determine behavior as follow:
+"
+" VCSCommandCommitOnWrite
+" This variable, if set to a non-zero value, causes the pending commit to
+" take place immediately as soon as the log message buffer is written. If
+" set to zero, only the VCSCommit mapping will cause the pending commit to
+" occur. If not set, it defaults to 1.
+"
+" VCSCommandDeleteOnHide
+" This variable, if set to a non-zero value, causes the temporary VCS result
+" buffers to automatically delete themselves when hidden.
+"
+" VCSCommand{VCSType}DiffOpt
+" This variable, if set, determines the options passed to the diff command
+" of the underlying VCS. Each VCS plugin defines a default value.
+"
+" VCSCommandDiffSplit
+" This variable overrides the VCSCommandSplit variable, but only for buffers
+" created with VCSVimDiff.
+"
+" VCSCommandDisableAll
+" This variable, if set, prevents the plugin or any extensions from loading
+" at all. This is useful when a single runtime distribution is used on
+" multiple systems with varying versions.
+"
+" VCSCommandDisableMappings
+" This variable, if set to a non-zero value, prevents the default command
+" mappings from being set.
+"
+" VCSCommandDisableExtensionMappings
+" This variable, if set to a non-zero value, prevents the default command
+" mappings from being set for commands specific to an individual VCS.
+"
+" VCSCommandEdit
+" This variable controls whether to split the current window to display a
+" scratch buffer ('split'), or to display it in the current buffer ('edit').
+" If not set, it defaults to 'split'.
+"
+" VCSCommandEnableBufferSetup
+" This variable, if set to a non-zero value, activates VCS buffer management
+" mode. This mode means that the buffer variable 'VCSRevision' is set if
+" the file is VCS-controlled. This is useful for displaying version
+" information in the status bar. Additional options may be set by
+" individual VCS plugins.
+"
+" VCSCommandMappings
+" This variable, if set, overrides the default mappings used for shortcuts.
+" It should be a List of 2-element Lists, each containing a shortcut and
+" function name pair.
+"
+" VCSCommandMapPrefix
+" This variable, if set, overrides the default mapping prefix ('<Leader>c').
+" This allows customization of the mapping space used by the vcscommand
+" shortcuts.
+"
+" VCSCommandResultBufferNameExtension
+" This variable, if set to a non-blank value, is appended to the name of the
+" VCS command output buffers. For example, '.vcs'. Using this option may
+" help avoid problems caused by autocommands dependent on file extension.
+"
+" VCSCommandResultBufferNameFunction
+" This variable, if set, specifies a custom function for naming VCS command
+" output buffers. This function will be passed the following arguments:
+"
+" command - name of the VCS command being executed (such as 'Log' or
+" 'Diff').
+"
+" originalBuffer - buffer number of the source file.
+"
+" vcsType - type of VCS controlling this file (such as 'CVS' or 'SVN').
+"
+" statusText - extra text associated with the VCS action (such as version
+" numbers).
+"
+" VCSCommandSplit
+" This variable controls the orientation of the various window splits that
+" may occur (such as with VCSVimDiff, when using a VCS command on a VCS
+" command buffer, or when the 'VCSCommandEdit' variable is set to 'split'.
+" If set to 'horizontal', the resulting windows will be on stacked on top of
+" one another. If set to 'vertical', the resulting windows will be
+" side-by-side. If not set, it defaults to 'horizontal' for all but
+" VCSVimDiff windows.
+"
+" VCSCommandVCSTypeOverride
+" This variable allows the VCS type detection to be overridden on a
+" path-by-path basis. The value of this variable is expected to be a List
+" of Lists. Each high-level List item is a List containing two elements.
+" The first element is a regular expression that will be matched against the
+" full file name of a given buffer. If it matches, the second element will
+" be used as the VCS type.
+"
+" Event documentation {{{2
+" For additional customization, VCSCommand.vim uses User event autocommand
+" hooks. Each event is in the VCSCommand group, and different patterns
+" match the various hooks.
+"
+" For instance, the following could be added to the vimrc to provide a 'q'
+" mapping to quit a VCS scratch buffer:
+"
+" augroup VCSCommand
+" au VCSCommand User VCSBufferCreated silent! nmap <unique> <buffer> q :bwipeout<cr>
+" augroup END
+"
+" The following hooks are available:
+"
+" VCSBufferCreated This event is fired just after a VCS command
+" output buffer is created. It is executed
+" within the context of the new buffer.
+"
+" VCSBufferSetup This event is fired just after VCS buffer setup
+" occurs, if enabled.
+"
+" VCSPluginInit This event is fired when the VCSCommand plugin
+" first loads.
+"
+" VCSPluginFinish This event is fired just after the VCSCommand
+" plugin loads.
+"
+" VCSVimDiffFinish This event is fired just after the VCSVimDiff
+" command executes to allow customization of,
+" for instance, window placement and focus.
+"
