----- Forwarded message from Harald Harders ----- I have uploaded leftidx-1_03.tar.gz to ftp.dante.de. It contains a new version of the leftidx package. Please replace all files in CTAN:macros/latex/contrib/leftidx by its contents. License stays LPPL.
The new version has been changed to dtx format and includes an English documentation. The implementation has been simplyfied using vphantom instead of mathchoice and different rules.
From the README:
This package enables left subscripts and superscripts in math mode. These subscripts and superscripts are automatically raised for better fitting to the symbol they belong to. ----- End forwarded message -----
Thanks for the upload. I installed it as suggested replacing the old version in CTAN:macros/latex/contrib/leftidx/
