echo.Usage:
echo.
echo.  alias [options] [alias=alias command]
echo.
echo.Options:
echo.
echo.  Note: Options MUST precede the alias definition.
echo.
echo.  /d [alias]     Delete an [alias].
echo.  /f [macrofile] Path to the [macrofile] you want to store the new alias in.
echo.                 Default: %cmder_root%\config\user_aliases.cmd
echo.  /reload        Reload the aliases file.  Can be used with /f argument.
echo.                 Default: %cmder_root%\config\user_aliases.cmd
echo.
echo. If alias is called with no parameters, it will display the list of existing
echo. aliases.
echo.
echo. In the alias command, you can use the following notations:
echo.
echo. ^^^^^^^^%% - %% signs in env vars must be escaped if preserving the variable
echo.         in he alias is desired. Variables in aliases surrounded by double
echo.         quotes only require '^^%%' vs '^^^^^^^^%%'
echo. $*    - allows the alias to assume all the parameters of the supplied
echo.         command.
echo. $1-$9 - Allows you to seperate parameter by number, much like %%1 in
echo.         batch.
echo. $T    - Command seperator, allowing you to string several commands
echo.         together into one alias.
echo.
echo. For more information, read DOSKEY /?
