+=head1 SUPPORTED URL SCHEMATA
+
+The following URL schemata are supported
+
+=over 4
+
+=item C<http://server/path/to/tlnet>
+
+Standard schema, is supported without any restrictions. If the (default)
+LWP method is used, this schema supports persistent connections.
+
+=item C<ftp://server/path/to/tlnet>
+
+If the (default) LWP method is used, this schema supports persistent connections.
+
+=item C<https://server/path/to/tlnet>
+
+If the (default) LWP method is used, this schema supports persistent connections.
+Some versions of C<wget> do not support this schema. Furthermore, even if
+C<wget> supports https, it might check the certificate. C<curl> generally
+supports https.
+
+=item C<user@machine:/path/to/tlnet>
+
+=item C<scp://user@machine/path/to/tlnet>
+
+=item C<ssh://user@machine/path/to/tlnet>

+These schemata use C<scp> to transfer files. The use of an C<ssh-agent>
+is highly recommended.

+=head1 ENVIRONMENT VARIABLES
+
+For ease in scripting and debugging, C<install-tl> will look for the
+following environment variables. They are not of interest for normal
+user installations.
+
+=over 4
+
+=item C<TEXLIVE_COMPRESSOR>
+
+This option allows selecting a different compressor program for
+backups and intermediate rollback containers. The order of selection is:
+
+=over 8
+
+=item 1.
+
+If the environment variable C<TEXLIVE_COMPRESSOR> is
+defined, use it; abort if it doesn't work. Possible values:
+C<lz4>, C<gzip>, C<xz>.
+
+
+=item 2.
+
+If lz4 is available (either from the system or TL) and working, use that.
+
+=item 3.
+
+If gzip is available (from the system) and working, use that.
+
+=item 4.
+
+If xz is available (either from the system or TL) and working, use that.
+
+=back
+
+lz4 and gzip are much faster in creating tlmgr's local backups.
+The unconditional use of xz for the tlnet containers is unaffected,
+to minimize download sizes.
+
+=item C<TEXLIVE_DOWNLOADER>
+
+=item C<TL_DOWNLOAD_PROGRAM>
+
+=item C<TL_DOWNLOAD_ARGS>
+
+These options allow selecting different download programs then the ones
+automatically selected by the installer. The order of selection is:
+
+=over 8
+
+=item 1.
+
+If the environment variable C<TEXLIVE_DOWNLOADER> is
+defined, use it; abort if the specified program doesn't work.
+Possible values: C<curl>, C<wget>.
+
+=item 2.
+
+If the environment variable C<TL_DOWNLOAD_PROGRAM> is
+defined (can be any value), use it together with
+C<TL_DOWNLOAD_ARGS>; abort if it doesn't work.
+
+=item 3.
+
+If LWP is available and working, use that (by far the most
+efficient method, as it supports persistent downloads).
+
+=item 4.
+
+If curl is available (from the system) and working, use that.
+
+=item 5.
+
+If wget is available (either from the system or TL) and working, use that.

+
+TL still provides C<wget> binaries for some platforms, so
+some download method should always be available.
