 (for those who come later, this is a fork from https://code.google.com/p/maphew/source/browse/other/create-leobat.bat, and the comments are made with regards to comparing the two.) L32: %%1 in place of %%*: The former will only pass the 1st parameter while the 2nd will pass everything. So when using %%1 the second and further files or parameters will be ignored. A fuller exploration of this at https://groups.google.com/d/msg/leo-editor/li9ILUWuNAs/3TZnm_U06KMJ L34-35: using @ at the beginning of a line is the same as "@echo off for this one line", so these two lines can be collapsed to one: echo @start "leo" /B "%pywexe%" "%~dp0launchLeo.py" "%%1" > leo.bat  L21, and eleswhere: While it's true that adding separator slash, like so %~dp1\python.exe, results in a double-slash when expanded, C:\Python27\\python.exe, I've yet to encounter a situation where the double-slash is a problem in practice. Windows doesn't seem to care. I prefer keeping the slash as it makes the code in the editor more readable, the variable is more distinct from the hard coded part. In the end though it's user preference, I just wanted to explain that it is deliberate and not an oversight. Use what's best for you.

 L32: Good question why I did that... no clue, really. It works, though, for my purposes. %%* is probably correct, and I will revise this. L34-35: Google says otherwise: http://www.instructables.com/id/Slightly-More-Advanced-Basic-Batch/step2/ECHO-OFFON-Command/ That being said, I did test this both with and without the @echo off line... and it only worked with the @echo off line. At least on my systems (2 win xp, 1 win 7 64). L21: It was complaining on my WinXP boxes, but that could be a security setting. Both of my WinXP boxes are the property of my employer, and they have some pretty crazy security protocols in place. Not sure if that has anything to do with it, but my WinXP boxes didn't like the extra slash at all.
