usage="$0 [OPTION]... TL-PLATFORM...

Update the TeX Live executables for each TL-PLATFORM (which must be a TL
platform name, e.g., i386-linux) from a build directory.

The new binaries are taken from the location specified by --bin-loc,
either a directory (whose contents are copied), or a tar file (which is
unpacked and then copied).

The output directory is computed relative to the location of this script
by default, or can be explicitly specified via --master.  An upper-level
directory is specified so multiple platforms can be installed.

This checks for broken symlinks, and symlinks with the svn:executable
property set (which would mess up Subversion; see the thread around
http://svn.haxx.se/users/archive-2007-03/1259.shtml.)

It also takes care of doing the explicit remove/add sequence Subversion
requires when a symlink is replaced by a file or vice versa.

Options:
  --bin-loc DIR-OR-TAR   use binaries from DIR-OR-TAR
  --master  DIR          install binaries to DIR/bin/TL-PLATFORM
                           [default is the bin dir relative to this script]

  --help                 display this help and exit
  --quiet, --silent      no progress reports
  --version              output version information and exit
