+# Wrapper script for nevernoid to allow read-only shared data
+# files, plus writable per-user highscore/settings in ~/nevernoid
+# Author: B. Watson (yalhcru@gmail.com)
+
+# How lame is this? The game opens the map files O_RDWR (read/write
+# access), even though it never attempts to write to them! Also, it
+# doesn't use fopen() to do this (I tried a LD_PRELOAD to fix it).
+
+# Because it's closed-source, I can't fix it, and because of this silliness,
+# the user directory needs to contain a *copy* of all the map files
+# rather than just symlinks to them. Fortunately they're small files.
+
+# A proper fix would involve either:
+# - The original author fixing the source and recompiling, or
+# - Someone well-versed in Linux-flavored 80x86 assembly to disassemble
+#   the code, find the offending O_RDWR byte, and replace with the value
+#   of O_RDONLY. This assumes that the call to open() is a separate call
+#   than the one that opens the highscores.dat/options.dat files for
+#   writing! This is complicated by the fact that the code was compiled
+#   with FreePascal instead of being written in the more familiar C...
