The convertESOMTR program is used to convert the units  in the ESO and MTR file 
from SI into  IP (or any other set of units).

To use follow these steps:

a) Copy convertESOMTR.exe into the main EnergyPlus directory.

b) Copy convert.txt into the main EnergyPlus directory.

c) Add the following lines to the EPL-RUN.BAT file if you use EP-Launch or the 
RunEPlus.bat file if you use that method.  The lines should be added directly 
after the call to EnergyPlus.exe.

IF EXIST convertESOMTR.exe convertESOMTR
IF EXIST ip.eso REN eplusout.eso eplusout.esoold
IF EXIST ip.eso REN ip.eso eplusout.eso
IF EXIST ip.mtr REN eplusout.mtr eplusout.mtrold
IF EXIST ip.mtr REN ip.mtr eplusout.mtr

The ReadVarsESO program will take these converted files and make them into 
normal CSV files.
