# The script takes an input file name (without an extension, so something like "emop.mfle.exp18") and running all the necessary commands to build the training files.

# 

# The command looks like this:
##		==============================================================================
## 		sh ./tess-script.sh <inputfile(s)> 
##		==============================================================================

# Where:
#		<inputfile(s)>: input file(s) with path  --(relative from the folder where your XSLT is running)
#		NOTE: the input file is the common prefix of the name of a set of tiff/box file pairs. i.e. leave off the .tif/.box
