[Unattended] Adobe reader script

[Matt_Fries]

Can anyone explain to me what this line in the adobe-reader.bat file is trying to do? I can't find any reference to what %m or %%m referrs to, and that script will randomly fail on me.

todo.pl "for %%m in (\"%TEMP%\adberdr\Adobe Reader 7.0*.msi\") do msiexec /qb /l* %SystemDrive%\netinst\logs\adobe-reader.txt /i \"%%m\" REBOOT=ReallySuppress"
