Save copy of scene in relative location

Using mel, how would I save a copy of a scene file in a relative location such as Project01/maya/renderScenes and later if I was working on another project (and Maya was set to that project) have the script save a copy of the scene file to Project02/maya/renderScenes

I'm assuming it's a combination of
string $currentSceneFilePath = `file -q -sceneName`;
to get the scene name

along with
file -f -save -type "mayaBinary";
(but how to check if it's a .ma or .mb?)

and some way to get the project directory then adding on "renderScenes"?

I'm very new to scripting so any examples would be very helpful.

Not sure how Mel does it but with Python it's only a 1 line command. So I guess you could do it this way.

string $currentScene;
string $currentPath;
string $pyCommand;

$currentScene = `file -q -sceneName`;
$pyCommand = "os.path.dirname(\"" + $currentScene + "\")";

python( "import os");
$currentPath = python( $pyCommand );

Here my $currentScene = P:/CGworkshop/project/scenes/temp.ma
Result of $currentPath = P:/CGworkshop/project/scenes

Thanks. Since Deadline's submission script is in mel I was hoping to attach it to the CustomSanityChecks.mel file so that a copy of the scene file gets stored in the project's directory (for future archiving). Can you call up a .py file from a .mel file or is it just better to just keep it all together in mel?

Also Deadline is able to swap the slashes for cross platform support (PC/Mac), wasn't sure if that needed to be written in as well or if it's simply handled in the main submission script.

Hmmm I'm pretty sure the Mel script is executed within Maya. But this might be safer.

$full = `file -q -sceneName`;
$short = `file -q -sceneName -shortName`;

$test = `substitute $short $full ""`;

$full --> P:/CGworkshop/project/scenes/temp.ma
$short --> temp.ma
So the substitute command is basically replace temp.ma with an empty string.

You can use this if you want to be sure about slash/back-slash

$test = toNativePath( $test )

I feel like I'm close but still don't know how to specify the relative path of $renderScenesFolder for the directory /maya/renderScenes folder. Any ideas?

$sceneName = `file -q -sceneName`;
$currentSceneDir = `workspace -q -dir`;
$currentDir = `workspace -q -rd`;

\\ How to set this from the $currentDir or $currentSceneDir ??
$renderScenesFolder = ???

string $source = $sceneName;
string $destination = $renderScenesFolder;

sysFile -copy $destination $source;
