echo.
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 [NOT] flagName command/program [parameters]
echo.
echo   /setPath         Generate a global varible %%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"
echo.
echo     call cexec "/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"
echo.
echo     call cexec NOT "/dontStartNotepad" "start" "notepad.exe"
echo.
echo   UNLESS you pass parameter to init.bat like:
echo.
echo     init.bat /dontStartNotepad
echo.
