-#
-# Linux script to move an existing rEFInd installation from one directory to another
-#
-# Usage:
-#
-# ./mvrefind.sh /path/to/source /path/to/destination
-#
-# Typically used to "hijack" or "unhijack" a Windows boot loader location or
-# to help convert a rEFInd installation made in BIOS mode to one that works
-# in EFI mode.
-#
-# Revision history:
-#
-# 0.6.3 -- Initial release
-#
-# Note: mvrefind.sh version numbers match those of the rEFInd package
-# with which they first appeared.

-# assist in comparisons. (This is reasonable because FAT is case-insensitive.)
