g:Lf_WorkingDirectoryMode                       *g:Lf_WorkingDirectoryMode*
    This option customizes LeaderF's working directory.
    e.g., >
    let g:Lf_WorkingDirectoryMode = 'Ac'
<
    c - the directory of the current working directory.(default)
    a - the nearest ancestor of current working directory that contains one of
        directories or files defined in |g:Lf_RootMarkers|. Fall back to 'c' if
        no such ancestor directory found.
    A - the nearest ancestor of current file that contains one of directories
        or files defined in |g:Lf_RootMarkers|. Fall back to 'c' if no such
        ancestor directory found.
    f - the directory of the current file.
    F - if the current working directory is not the direct ancestor of current
        file, use the directory of the current file as LeaderF's working
        directory, otherwise, same as 'c'.
    Note: if "f", "F" is included with "a" or "A", use the behavior of "f" or
    "F"(as a fallback) when a root can't be found.

" Usage
" -----
" First of all, you must execute gtags(1) at the root of source directory
" to make tag files. Assuming that your source directory is '/var/src',
" it is neccessary to execute the following commands.
"
" [Load vim]
"	$ cd /var/src
"	$ gtags
"	$ vim
" [Load gtags-cscope]
"	:GtagsCscope <ENTER>            (in vim command line)
"
" Basic command
" -------------
" Then you can use cs commands except for the 'd'(2) command.
" Profitable commands are assigned to keys like follows:
"
"	explanation		command	
"	----------------------------------------------------------
"	Find symbol		:cs find 0 or s
"	Find definition		:cs find 1 or g
"	Find functions called by this function	(not implemented)
"	Find reference		:cs find 3 or c
"	Find text string	:cs find 4 or t
"	Find egrep pattern	:cs find 6 or e
"	Find path		:cs find 7 or f
"	Find include file	:cs find 8 or i
"	Find assignments	:cs find 9 or a
"
" You can move tag list using:
"	Go to the next tag	 :tn
"	Go to the previous tag	 :tp
"	Pop tag stack		 :pop
