+
+### Description
+#
+# This script replaces broken hardcoded strings in binary files (e.g. maps)
+# with another string given by the user.
+#
+# The input and ouput strings are given by the file passed as first argument,
+# which should be of the form:
+#
+# old string<TAB>new string
+# other old string<TAB>other new string
+# etc.
+#
+# The strings are fixed by binary replacements of their hex code. The hex
+# representation of a string starts with its length on four bytes, but in
+# this script we currently only fix the fourth byte (the others are typically
+# null), which means we support strings up to 255 chars.
+#
+# The binary files to fix are passed as second and optionally more arguments.
+#
+
+### Usage
+#
+# ./Misc/fix-hardcoded-hex-paths.sh [file describing fixes] [maps to fix]
+#
+# e.g.:
+#
+# ./Misc/fix-hardcoded-hex-paths.sh Misc/list-hardcoded-paths-fixes.txt Data/Maps/jendraz*
+#
