+=head1 QUOTING
+
+You can quote ordinary parameters using either single or double
+quotes.  For example:
+
+ add "file with a space.img"
+
+ rm '/file name'
+
+ rm '/"'
+
+A few commands require a list of strings to be passed.  For these, use
+a space-separated list, enclosed in quotes.  For example:
+
+ vgcreate VG "/dev/sda1 /dev/sdb1"
+
+=head1 COMMENTS
+
+Any line which starts with a I<#> character is treated as a comment
+and ignored.  The I<#> can optionally be preceeded by whitespace,
+but B<not> by a command.  For example:
+
+ # this is a comment
+         # this is a comment
+ foo # NOT a comment
+
+Blank lines are also ignored.
