+Subject: [PATCH] main.c: rework logic to find def1, def2 and def3 files
+
+The current logic to find def1, def2 and def3 first tries to find them
+in the local directory, and if they are not available, find them in
+/usr/share.
+
+However, this doesn't work if rpiboot and its related files are
+installed, but not in /usr. In order to address this use-case, this
+commit reworks the logic to find the file path.
+
+A new function, getfilepath() is created. If the requested file is
+available in the current directory, it is used. If not, then the path to
+the file is inferred from the location of the currently running
+program. I.e if we run /home/foo/sys/bin/rpiboot, then we will search
+def1 in usbbootcode.bin in
+/home/foo/sys/bin/../share/rpiboot/usbbootcode.bin.
+
+This continues to address the case of an installation in /usr, while
+allowing installation in other locations as well.
