# Errors/mistakes
# - no verif ran by root
# - no verif TrueCrypt is NOT running
# - no verif all libfiles exist beforehand
# - pkgconfig is not recreated on dest, the 2 *.pc files are not copied to the right location
# - symlinks not copied: he handles only the 7 files, there are 16 symlinks that become orphans
# 
# Read this article: https://lazymind.me/2014/10/install-truecrypt-on-mac-osx-yosemite-10-10/
# Opened an "old" 7.1a dmg (e.g. dump the "insecure" FUD) 
# Copy out "TrueCrypt 7.1a.mpkg" to ~/Downloads
# Edited `distribution.dist` as explained in above url
# Opened the the mpkg/Contents/Packages
# Confirmed 23 lib entries in the 2 Fuse pkgs. OSXFUSECore.pkg OSXFUSEMacFUSE.pkg
# * The 3rd pkg, MacFUSE.pkg, doesnt carry lib files
# Installed TrueCrypt (after hacking the distribution.dist file)
# - tested that it opens an existing vol, creating new vol == ok (before moving libs)
# - wrote script and run
# - repeat tests
#
# Includes
# There're 9 files under /usr/local/include, they can be moved under /Apps.../Include
# osxfuse/fuse/fuse.h
# osxfuse/fuse/fuse_common.h
# osxfuse/fuse/fuse_common_compat.h
# osxfuse/fuse/fuse_compat.h
# osxfuse/fuse/fuse_darwin.h
# osxfuse/fuse/fuse_lowlevel.h
# osxfuse/fuse/fuse_lowlevel_compat.h
# osxfuse/fuse/fuse_opt.h
# osxfuse/fuse.h
#
# caveats
# This script isn't idempotent. If ran a 2nd time, we have symlinks under lib ...
# and it will end up in infinite symlink loop ....
