+echo CExec - Conditional Exec
+echo.
+echo Handles with custom arguments for cmder's init.bat.
+echo   written by xiazeyu, inspired DRSDavidSoft.
+echo.
+echo Usage:
+echo.
+echo cexec /setPath [NOT] flagName command/program [parameters]
+echo.
+echo   /setPath         Generate a global varibles %%ccall%% and  %%cexec%% for
+echo                    quicker use. Following arguments will be ignored.
+echo.
+echo   NOT              Specifies that cexec should carry out
+echo                    the command only if the flag is missing.
+echo.
+echo   /[flagName]      Specifies which flag name is to detect. It's recommand
+echo                    to use a pair of double quotation marks to wrap
+echo                    your flag name to avoid exceed expectation.
+echo.
+echo   command/program  Specifies the command to carry out if the
+echo                    argument name is detected. It's recommand to
+echo                    use a pair of double quotation marks to
+echo                    wrap your command to avoid exceed expectation.
+echo.
+echo   parameters       These are the parameters passed to the command/program.
+echo                    It's recommand to use a pair of double quotation marks 
+echo                    to wrap your flag name to avoid exceed expectation.
+echo.
+echo Examples:
+echo.
+echo   These examples are expected to be written in %cmder_root%/config/user-profile.cmd
+echo   CExec evaluates the environment varible "CMDER_USER_FLAGS" and conditionally
+echo   caries out actions based on flags that are passed.
+echo.
+echo   Case 1:
+echo.
+echo   The following command in `user_profile.cmd` would execute "notepad.exe" and continue running the `user_profile.cmd`
+echo.
+echo     "%ccall%" "/startNotepad" "start" "notepad.exe"
+echo.
+echo   If you pass parameter to init.bat like:
+echo.
+echo     init.bat /startNotepad
+echo.
+echo   Case 2:
+echo.
+echo   The following command in `user_profile.cmd` would execute "notepad.exe" and stop running the `user_profile.cmd`
+echo.
+echo     "%cexec%" NOT "/dontStartNotepad" "start" "notepad.exe"
+echo.
+echo   UNLESS you pass parameter to init.bat like:
+echo.
+echo     init.bat /dontStartNotepad
