  4. Re-start your apache to re-load the config if necessary.
  5. Load up the page "/roundup/roundup.cgi/<instance name>/index" where
     instance name is the name you nominated in ROUNDUP_INSTANCE_HOMES.
+ 6. To use the CGI script unchanged, which allows much easier updates,
+    add these directives to your "httpd.conf":
+        SetEnv ROUNDUP_LOG "/var/log/roundup.log"
+        SetEnv ROUNDUP_INSTANCE_HOMES "Default=/usr/local/share/roundup"
+        SetEnv ROUNDUP_DEBUG "0"
+ 7. On Windows, write a batch file "roundup.bat" similar to the one below
+    and place it into your cgi-bin directory:
+        @echo off
+        set ROUNDUP_LOG=c:\data\roundup\cgi.log
