+Configuration Parameter Types
+=============================
+Configuration parameter values have different data types.
+Unfortunately, the type currently must be guessed from the description
+(consider contributing to the doc to help improve it). In general, the
+following types are used:
+
+- **numbers**
+
+  The traditional integer format.  Numbers may include '.' and ','
+  for readability. So you can for example specify either "1000" or
+  "1,000" with the same result. Please note that rsyslogd simply
+  *ignores* the punctuation. From it's point of view, "1,,0.0.,.,0"
+  also has the value 1000.
+
+- **sizes**
+
+  Used for things like file size, main message queue sizes and the like.
+  These are integers, but support modifier after the number part.
+  For example, 1k means 1024. Supported are
+  k(ilo), m(ega), g(iga), t(era), p(eta) and e(xa). Lower case letters
+  refer to the traditional binary definition (e.g. 1m equals 1,048,576)
+  whereas upper case letters refer to their new 1000-based definition (e.g
+  1M equals 1,000,000).
+
+- **complete line**
+
+  A string consisting of multiple characters. This is relatively
+  seldom used and sometimes looks confusing (rsyslog v7+ has a much better
+  approach at these types of values).
+
+- **single word**
+
+  This is used when only a single word can be provided. A "single
+  word" is a string without spaces in it. **No** quoting is necessary
+  nor permitted (the quotes would become part of the word).
+
+- **character**
+
+  A single (printable) character. Must **not** be quoted.
+
+- **boolean**
+
+  The traditional boolean type, specified as "on" (1) or "off" (0).
+
+Note that some other value types are occasionally used. However, the
+majority of types is one of those listed above. The list is updated
+as need arises and time permits.
