+This UPGRADE.txt file is a command-line syntax reminder for
+experienced PmWiki administrators.  For full documentation on
+upgrading Pmwiki, see the bundled PmWiki.Upgrades page or visit
+
+  http://www.pmwiki.org/wiki/PmWiki/Upgrades
+
+See also these related pages:

+  http://www.pmwiki.org/wiki/PmWiki/BackupAndRestore
+  http://www.pmwiki.org/wiki/PmWiki/Subversion
+
+The examples assume your PmWiki site is in a ./pmwiki/
+directory (a directory named "pmwiki" immediately below the
+working directory).
+
+Backing up (always a good idea!):
+
+  tar -zcvf ~/pmwiki-backup.tar.gz pmwiki
+  zip -9r  ~/pmwiki-backup.zip pmwiki
+
+Or, to keep backups organized by date:
+
+  tar -zcvf ~/pmwiki-site-`date +%Y%m%d%M`.tar.gz pmwiki
+  zip -9r  ~/pmwiki-site-`date +%Y%m%d%M`.zip pmwiki
+
+The latest release is available here:
+
+  http://www.pmichaud.com/pub/pmwiki/pmwiki-latest.tgz

+
+Example download commands:
+

+  links http://www.pmichaud.com/pub/pmwiki/pmwiki-latest.tgz
+  lynx http://www.pmichaud.com/pub/pmwiki/pmwiki-latest.tgz
