+" Last Modified: September 10, 2007
+"
+" Overview
+" --------
+" The grep plugin integrates the grep, fgrep, egrep, and agrep tools with
+" Vim and allows you to search for a pattern in one or more files and jump
+" to them.
+"
+" To use this plugin, you need the grep, fgrep, egrep, agrep, find and
+" xargs utilities. These tools are present in most of the Unix installations.
+" For MS-Windows systems, you can download the GNU grep and find utilities
+" from the following sites:
+"
+" http://gnuwin32.sourceforge.net/packages/grep.htm
+" http://gnuwin32.sourceforge.net/packages/findutils.htm
+"
+" Installation
+" ------------
+" 1. Copy the grep.vim file to the $HOME/.vim/plugin or $HOME/vimfiles/plugin
+" or $VIM/vimfiles/plugin directory.
+" Refer to the following Vim help topics for more information about Vim
+" plugins:
+" :help add-plugin
+" :help add-global-plugin
+" :help runtimepath
+" 2. If the grep executables are not already present in one of the directories
+" in the PATH environment variable, then set the Grep_Path and other _Path
+" variables to point to the location of the grep utilites in the .vimrc
+" file.
+" 3. Restart Vim.
+" 4. You can now use the ":Grep" and other commands to search for patterns in
+" files.
+"
+" Usage
+" -----
+" The grep.vim plugin introduces the following Vim commands:
+"
+" :Grep - Search for the specified pattern in the specified files
+" :GrepAdd - Same as ":Grep" but adds the results to the current results
+" :Rgrep - Run recursive grep
+" :RgrepAdd - Same as ":Rgrep" but adds the results to the current results
+" :GrepBuffer - Search for a pattern on all open buffers
+" :GrepBufferAdd - Same as ":GrepBuffer" but adds the results to the current
+" results
+" :Bgrep - Same as :GrepBuffer
+" :BgrepAdd - Same as :GrepBufferAdd
+" :GrepArgs - Search for a pattern on all the Vim argument
+" filenames (:args)
+" :GrepArgsAdd - Same as ":GrepArgs" but adds the results to the current
+" results
+" :Fgrep - Run fgrep
+" :FgrepAdd - Same as ":Fgrep" but adds the results to the current
+" results
+" :Rfgrep - Run recursive fgrep
+" :RfgrepAdd - Same as ":Rfgrep" but adds the results to the current
+" results
+" :Egrep - Run egrep
+" :EgrepAdd - Same as ":Egrep" but adds the results to the current
+" results
+" :Regrep - Run recursive egrep
+" :RegrepAdd - Same as ":Regrep" but adds the results to the current
+" results
+" :Agrep - Run agrep
+" :AgrepAdd - Same as ":Agrep" but adds the results to the current
+" results
+" :Ragrep - Run recursive agrep
+" :RagrepAdd - Same as ":Ragrep" but adds the results to the current
+" results
+"
+" The above commands can be invoked like this:
+"
+" :Grep [<grep_options>] [<search_pattern> [<file_name(s)>]]
+" :Rgrep [<grep_options>] [<search_pattern> [<file_name(s)>]]
+" :Fgrep [<grep_options>] [<search_pattern> [<file_name(s)>]]
+" :Rfgrep [<grep_options>] [<search_pattern> [<file_name(s)>]]
+" :Egrep [<grep_options>] [<search_pattern> [<file_name(s)>]]
+" :Regrep [<grep_options>] [<search_pattern> [<file_name(s)>]]
+" :Agrep [<grep_options>] [<search_pattern> [<file_name(s)>]]
+" :Ragrep [<grep_options>] [<search_pattern> [<file_name(s)>]]
+"
+" :GrepAdd [<grep_options>] [<search_pattern> [<file_name(s)>]]
+" :RgrepAdd [<grep_options>] [<search_pattern> [<file_name(s)>]]
+" :FgrepAdd [<grep_options>] [<search_pattern> [<file_name(s)>]]
+" :RfgrepAdd [<grep_options>] [<search_pattern> [<file_name(s)>]]
+" :EgrepAdd [<grep_options>] [<search_pattern> [<file_name(s)>]]
+" :RegrepAdd [<grep_options>] [<search_pattern> [<file_name(s)>]]
+" :AgrepAdd [<grep_options>] [<search_pattern> [<file_name(s)>]]
+" :RagrepAdd [<grep_options>] [<search_pattern> [<file_name(s)>]]
+"
+" :GrepBuffer [<grep_options>] [<search_pattern>]
+" :Bgrep [<grep_options>] [<search_pattern>]
+" :GrepArgs [<grep_options>] [<search_pattern>]
+"
+" :GrepBufferAdd [<grep_options>] [<search_pattern>]
+" :BgrepAdd [<grep_options>] [<search_pattern>]
+" :GrepArgsAdd [<grep_options>] [<search_pattern>]
+"
+" In the above commands, all the arguments are optional.
+"
+" You can specify grep options like -i (ignore case) or -w (search for a word)
+" to the above commands. If the <grep_options> are not specified, then the
+" default grep options specified by the variable Grep_Default_Options is
+" used.
+"
+" You can specify the grep pattern to search as an argument to the above
+" commands. If the <search_pattern> is not specified, then you will be
+" prompted to enter a search pattern. By default, the keyword under the cursor
+" is displayed for the search pattern prompt. You can accept the default or
+" modify it.
+"
+" The search pattern is automatically enclosed by the character specified in
+" the Grep_Shell_Quote_Char variable. You should not enclose the search
+" pattern with a shell escape character.
+"
+" If you want to specify a search pattern with space characters or a
+" multi-word pattern, then you should use the Grep command pattern input
+" prompt to supply the pattern.
+"
+" You can specify one or more file names (or file patterns) to the above
+" commands. If the <file_names> are not specified, then you will be prompted
+" to enter file names. By default, the pattern specified by the
+" Grep_Default_Filelist variable is used. To specify the file name(s) as an
+" argument to the above commands, you have to specify the search pattern also.
+"
+" When you enter only the command name, you will be prompted to enter the
+" search pattern and the files in which to search for the pattern. By default,
+" the keyword under the cursor is displayed for the search pattern prompt.
+" Depending on the command, you may prompted for additional parameters like
+" the directories to search for the pattern.
+"
+" You can retrieve previously entered values for the Grep prompts using the up
+" and down arrow keys. You can cancel the command by pressing the escape key.
+" You can use CTRL-U to erase the default shown for the prompt and CTRL-W to
+" erase the previous word in the prompt. For more information about editing
+" the prompt, read ':help cmdline-editing' Vim help topic.
+"
+" After invoking any of the grep commands, you can cancel the command, when
+" you are prompted for a search pattern or file names or a directory by
+" pressing the <Esc> key. You cannot cancel (or kill) the
+" grep/fgrep/egrep/agrep commands after the external command is invoked.
+"
+" The GrepAdd, RgrepAdd and other *Add commands append the search output to
+" the current search output. This is useful if you want to see the search
+" results for multiple patterns at the same time. These commands are available
+" only in Vim version 7.0 and above.
+"
+" You can map a key to invoke any of the above commands. For example, the
+" following map invokes the :Grep command to search for the keyword under the
+" cursor:
+"
+" nnoremap <silent> <F3> :Grep<CR>
+"
+" The output of the grep command will be listed in the Vim quickfix window.
+" 1. You can select a line in the quickfix window and press <Enter> or double
+" click on a match to jump to that line.
+" 2. You can use the ":cnext" and ":cprev" commands to the jump to the next or
+" previous output line.
+" 3. You can use the ":colder" and ":cnewer" commands to go between multiple
+" grep quickfix output windows.
+" 4. The quickfix window need not be opened always to use the grep output.
+" You can close the quickfix window and use the quickfix commands to jump
+" to the grep matches. Use the ":copen" command to open the quickfix
+" window again.
+"
+" For more information about other quickfix commands read ":help quickfix"
+"
+" When using GUI Vim, the Tools->Search menu item with a few sub-menu items is
+" created for few variations of the search command.
+"
+" Configuration
+" -------------
+" By changing the following variables you can configure the behavior of this
+" plugin. Set the following variables in your .vimrc file using the 'let'
+" command.
+"
+" The 'Grep_Path' variable is used to locate the grep utility. By default,
+" this is set to grep. You can change this using the let command:
+"
+" :let Grep_Path = 'd:\tools\grep.exe'
+"
+" The 'Fgrep_Path' variable is used to locate the fgrep utility. By default,
+" this is set to fgrep. You can change this using the let command:
+"
+" :let Fgrep_Path = 'd:\tools\fgrep.exe'
+"
+" The 'Egrep_Path' variable is used to locate the egrep utility. By default,
+" this is set to egrep. You can change this using the let command:
+"
+" :let Egrep_Path = 'd:\tools\egrep.exe'
+"
+" The 'Agrep_Path' variable is used to locate the agrep utility. By default,
+" this is set to agrep. You can change this using the let command:
+"
+" :let Agrep_Path = 'd:\tools\agrep.exe'
+"
+" The 'Grep_Find_Path' variable is used to locate the find utility. By
+" default, this is set to d:\tools\find.exe. You can change this using the let
+" command:
+"
+" :let Grep_Find_Path = 'd:\tools\find.exe'
+"
+" The 'Grep_Xargs_Path' variable is used to locate the xargs utility. By
+" default, this is set to xargs. You can change this using the let
+" command:
+"
+" :let Grep_Xargs_Path = 'd:\tools\xargs.exe'
+"
+" When running any one of the Grep commands, you will be prompted for the
+" files in which to search for the pattern. The 'Grep_Default_Filelist'
+" variable is used to specify to default for this prompt. By default, this
+" variable is set to '*'. You can specify multiple matching patterns separated
+" by spaces. You can change this settings using the let command:
+"
+" :let Grep_Default_Filelist = '*.[chS]'
+" :let Grep_Default_Filelist = '*.c *.cpp *.asm'
+"
+" The 'Grep_Default_Options' is used to pass default command line options to
+" the grep/fgrep/egrep/agrep utilities. By default, this is set to an empty
+" string. You can change this using the let command:
+"
+" :let Grep_Default_Options = '-i'
+"
+" The 'Grep_Skip_Dirs' variable specifies the list of directories to skip
+" while doing recursive searches. By default, this is set to 'RCS CVS SCCS'.
+" You can change this using the let command:
+"
+" :let Grep_Skip_Dirs = 'dir1 dir2 dir3'
+"
+" The 'Grep_Skip_Files' variable specifies the list of files to skip while
+" doing recursive searches. By default, this is set to '*~ *,v s.*'. You can
+" change this using the let command:
+"
+" :let Grep_Skip_Files = '*.bak *~'
+"
+" By default, when you invoke the Grep commands the quickfix window will be
+" opened with the grep output. You can disable opening the quickfix window,
+" by setting the 'Grep_OpenQuickfixWindow' variable to zero:
+"
+" :let Grep_OpenQuickfixWindow = 0
+"
+" You can manually open the quickfix window using the :cwindow command.
+"
+" By default, for recursive searches, the 'find' and 'xargs' utilities are
+" used. If you don't have the 'xargs' utility or don't want to use the
+" 'xargs' utility, " then you can set the 'Grep_Find_Use_Xargs' variable to
+" zero. If this is set to zero, then only the 'find' utility is used for
+" recursive searches:
+"
+" :let Grep_Find_Use_Xargs = 0
+"
+" To handle file names with space characters in them, the xargs utility
+" is invoked with the '--null' argument. If the xargs utility in your system
+" doesn't accept the '--null' argument, then you can change the
+" Grep_Xargs_Options variable. For example, to use the '--print0' xargs
+" argument, you can use the following command:
+"
+" :let Grep_Xargs_Options = '--print0'
+"
+" The Grep_Cygwin_Find variable should be set to 1, if you are using the find
+" utility from the cygwin package. This setting is used to handle the
+" difference between the backslash and forward slash path separators.
+"
+" :let Grep_Cygwin_Find = 1
+"
+" The 'Grep_Null_Device' variable specifies the name of the null device to
+" pass to the grep commands. This is needed to force the grep commands to
+" print the name of the file in which a match is found, if only one filename
+" is specified. For Unix systems, this is set to /dev/null and for MS-Windows
+" systems, this is set to NUL. You can modify this by using the let command:
+"
+" :let Grep_Null_Device = '/dev/null'
+"
+" The 'Grep_Shell_Quote_Char' variable specifies the quote character to use
+" for protecting patterns from being interpreted by the shell. For Unix
+" systems, this is set to "'" and for MS-Window systems, this is set to an
+" empty string. You can change this using the let command:
+"
+" :let Grep_Shell_Quote_Char = "'"
+"
+" The 'Grep_Shell_Escape_Char' variable specifies the escape character to use
+" for protecting special characters from being interpreted by the shell. For
+" Unix systems, this is set to '\' and for MS-Window systems, this is set to
+" an empty string. You can change this using the let command:
+"
+" :let Grep_Shell_Escape_Char = "'"
+"
