+ def sisu_0_42
+ <<WOK
+ SiSU 0.42 (a subset of 1.0) is the same as 0.38 with the introduction of some additional endnote types,
+
+ Introduces some varations on endnotes, in particular the use of the asterisk
+ ~{* for example for describing an author }~ and ~{** for describing a second author }~
+
+ * for example for describing an author
+
+ ** for describing a second author
+
+ and ~[* my note ]~ or ~[+ another note ]~ which numerically increments an
+ asterisk and plus respectively

+ *1 my note
+ +1 another note
+
+WOK
+ end
+ def sisu_0_38
+ <<WOK
+
+ SiSU 0.38 (a subset of 1.0) introduced alternative experimental header and heading/structure markers,
+
+ @headername: and headers :A~ :B~ :C~ 1~ 2~ 3~
+
+ as the equivalent of (the superceded)
+
+ 0~headername and headers 1~ 2~ 3~ 4~ 5~ 6~
+
+ The internal document markup of SiSU 0.16 remains valid and standard
+ Though note that SiSU 0.37 introduced a new file naming convention
+
+ SiSU has in effect two sets of levels to be considered, using 0.38 notation
+ A-C headings/levels, pre-ordinary paragraphs /pre-substantive text, and
+ 1-3 headings/levels, levels which are followed by ordinary text.
+ This may be conceptualised as levels A,B,C, 1,2,3, and using such letter
+ number notation, in effect:
+ A must exist, optional B and C may follow in sequence (not strict)
+ 1 must exist, optional 2 and 3 may follow in sequence
+ i.e. there are two independent heading level sequences A,B,C and 1,2,3
+ (using the 0.16 standard notation 1,2,3 and 4,5,6)
+ on the positive side:
+ * the 0.38 A,B,C,1,2,3 alternative makes explicit an aspect of structuring
+ documents in SiSU that is not otherwise obvious to the newcomer (though
+ it appears more complicated, is more in your face and likely to be
+ understood fairly quickly)
+ * the substantive text follows levels 1,2,3 and it is 'nice' to do
+ most work in those levels
+WOK
+ end
+ def sisu_0_37
+ <<WOK
+
+ SiSU 0.37 introduced the file naming convention, that remains in use in SiSU
+ v1 and v2, using the file extensions .sst .ssm and .ssi
+ to replace .s1 .s2 .s3 .r1 .r2 .r3 and .si
+
+ this is captured by the following file 'rename' instruction:
+
+ rename 's/\.s[123]$/\.sst/' *.s{1,2,3}
+ rename 's/\.r[123]$/\.ssm/' *.r{1,2,3}
+ rename 's/\.si$/\.ssi/' *.si

+ The internal document markup remains unchanged, from SiSU 0.16
+WOK

+ def sisu_0_16
+ <<WOK
+
+ SiSU 0.16 (0.15 development branch) introduced the use of

+ the header 0~ and headings/structure 1~ 2~ 3~ 4~ 5~ 6~
+
+ in place of the 0.1 header, heading/structure notation
