+.SH NAME
+getnonfreefonts \- download and install fonts which cannot be
+distributed on a CD
+.LP
+getnonfreefonts-sys \- download and install fonts system\-wide which
+cannot be distributed on a CD
+
+.SH SYNOPSIS
+
+.BI "getnonfreefonts [" options "] [" fontlist ]
+.sp
+.BI "getnonfreefonts-sys [" options "] [" fontlist ]
+
+.SH DESCRIPTION
+Some font suppliers provide fonts which can be used freely but they
+disallow that money is charged for the distribution.  Hence, for
+distributions on CD or DVD it is usually impossible to include
+these fonts.
+
+.B "getnonfreefonts"
+is a script which downloads and installs these fonts.  Actually, it
+first downloads the program
+.BI "getfont"<year>
+from tug.org which is then executed.
+.BI "getfont"<year>
+does the real work.  It will be updated occasionally to support more
+fonts.  
+.I <year>
+denotes the TeXLive release.
+
+.B getnonfreefonts
+and
+.B getnonfreefonts-sys
+are identical except that
+.B getnonfreefonts
+installs files to $TEXMFHOME
+while
+.B getnonfreefonts-sys
+installs files to $TEXMFLOCAL.
+
+.BI "getfont"<year>
+will not be installed permanently on your system.  It only
+exists in a temporary directory while 
+.BI getnonfreefonts
+is running.
+
+Run
+.B getnonfreefonts --lsfonts
+to get a list of supported fonts.
+
+.SH OPTIONS
+
+.TP
+.BR "-a" , " --all"
+.rg
+Install all fonts.
+
+.TP
+.BR "-d" , " --debug"
+.rg
+Provide additional messages for debugging.  These messages are sent to
+STDERR.
+
+.TP
+.BR "-f" , " --force"
+.rg
+Install fonts even if they are installed already.
+
+.TP
+.BR "-h" , " --help"
+.rg
+Print a help message.  Nothing is installed but the directories where
+the fonts will be installed and the temporary directory are shown.
+.BI "<" PID ">" 
+will be replaced by the process ID of the current
+process. 
+
+.TP
+.BR "-H" , " --http"
+.rg
+Use HTTP instead of FTP.  This is useful if you are behind a firewall
+which is blocking FTP.  However, you can't install fonts which are on
+FTP servers.  Currently this is only "Adobe Euro".
+
+.TP
+.BR "-l" , " --lsfonts"
+.rg
+List all available fonts and tell whether they are installed already. 
+
+.TP
+.BR "-r" , " --refreshmap"
+.rg
+Register 
+.B map 
+files for already installed fonts and run 
+.B updmap. 
+This is needed after upgrading TeX Live to a newer release.
+
+.TP
+.B --sys
+.rg
+If you call
+.B getnonfreefonts
+with the
+.B --sys
+option, it behaves exactly as
+.BR "getnonfreefonts-sys".
+
+.TP
+.BR "-v" , " --verbose"
+.rg
+Be more verbose.  This option is only needed for debugging.
+
+.TP
+.BR "--version"
+.rg
+Print version number.
+
+.SH ENVIRONMENT
+One of the environment variables
+.BR "TMP" , " TEMP" ,
+or 
+.B  TMPDIR
