	  expressions can be used
	- changed "fprintf(stderr..." to "cerr << ..." in regexp.h
	- Added c, d & s options to the PerlString::tr() function
	- fixed some bugs in tr() range processing

v1.3	- Cleaned up MArray constructor - Thanks Michael
	- Cleaned up tr() some more. Fixed d and s and c option.
	- Added PerlStringList PerlString::split()
	- Added operator>>() for PerlString
	- Added operator>>() for PerlStringList

v1.4	- Implemented PerlList::sort()
	- Implemented PerlString:s(), the substitute command
	- Added subexpression replacement in PerlString:s()
	- split out the test code from perlclass.c++ into perltest.c++
	- fixed bug in substr() for default length
	- Added the 'g' option for PerlString:s()
	- Changed the way that PerlString::m(s, l) works, now the list
	  'l' is reset first.
	- Added PerlList<T>:operator void*() so a list can be used in
	  a conditional, and returns 0 if the list is empty
	- Added PerlStringList m(pat, str) to match perl syntax
	- Added case insensitive matching to Regexp class
	- Added 'i' option to PerlStringList::grep
	- Added 'i' option to the m() functions
	- Added 'i' option to PerlString::s() function
	- Added a generic Makefile - Hooray

v1.5	- Added PerlList<T>::isempty()
	- Added PerlListBase instead of MArray, which uses the empty
	  space technique at front and back as suggested by MG.
	- Changed PerlListBase::operator[]() to allow indexing non-existing
	  elements, and implemented auto grow.
	- Fixed splice() to append to end of list if offset is > number
	  of items in list, this matches perls behaviour
	- Fixed potential overrunning end of string in substring class
	- added a const version of Binar::key() and value()
	- Replaced MArray with VarString class for improved string
	  handling - ie faster

v1.6	- Changed VarString::operator=() to not delete and new if
	  enough is already allocated. (as per MG)
	- Fixed a grow() bug in VarString::add(char)
	- Sped up tr() by replacing lookup with indexed array for search
	- Fixed split() so it splits on whitespace by default
	- Added a PerlString::substring(Range) for convenience
	- Fixed split() to use regular expression for pattern, as per
	  Perl (including subexpressions)
	- Fixed pop() to not give an assertion error when list is empty
	  but to return an undefined element instead
	- Added special awk case to split("' '")
	- Added special case for empty string in split("")

v1.7	- Changed Names from Perl... to SP... for release to alt.sources
	- Added typdefs so old names would still work
	- renamed all files from perlclass.* to splash.*
	- Put a check in SPString::index() for offset < 0

v1.8	- added comparison operators to SPString to allow permutations
	  of comparisons with char *'s.
	- added Slice and SubList to handle SPList slices
	- Added intersection and union of Ranges and test for validity
	- Added operator++ for extendng end of range by one
	- Stored length of Range rather than calculate it every time

V1.9
	- fixed the assert error in Range/Regexp when a match is zero
          length	
	- fixed slicetst.cpp
	- Moved stuff around to get rid of BC4.0 warnings about inlines
	- Added the SPListIter functions in a separate header file
	- Rewrite SPListBase::grow() to re-center first, before trying to re-allocate.
	  This stops the unlimited growing of lists being used as fifos.
	- Fixed a bug in VarString::remove() (- Thanks Tor)
	- added SPListIter class in file splistit.h
	- Added explicit templates for gcc-2.6.3
