1. the file name lists ought to be restricted to "*.h" anyway

2.  C++ files may be named .../[a-z]++/... also
3.  the original egrep pattern was not finding "__MIPSEL".
    I am not enough of a regexp person to know why.
4.  Adding copyright year and attribution to output
5.  Add copyright date and attribution
6.  Clarify a bunch of comments
7.  Remove dead template text
8.  Correct the counting of regular expressions
