'''from the EPICS documentation regarding dbLoadTemplate():
dbLoadTemplate(char *subfile, char *substitutions)
This IOC command reads a template substitutions file which
provides instructions for loading database instance files
and gives values for the $(xxx) macros they may contain.
This command performs those substitutions while loading the
database instances requested.
The subfile parameter gives the name of the template substitution file to be used.
The optional substitutions parameter may contain additional global macro values,
which can be overridden by values given within the substitution file.
