+By default, compression and download programs provided by the system,

+Live.

+This can create problems with systems that are too old, and so can be
+overridden by setting the environment variable \f(CW\*(C`TEXLIVE_PREFER_OWN\*(C'\fR to
+1. In this case, executables shipped with \s-1TL\s0 will be preferred.

+Extra compression/download programs not provided by \s-1TL,\s0 such as gzip,
+lwp, and curl, are still checked for on the system and used if
+available, per the above. \f(CW\*(C`TEXLIVE_PREFER_OWN\*(C'\fR only applies when the
+program being checked for is shipped with \s-1TL,\s0 namely the lz4 and
+xz compressors and wget downloader.

+Exception: on Windows, the \f(CW\*(C`tar.exe\*(C'\fR shipped with \s-1TL\s0 is always used,
