+NOTES
+-----
+
+I've checked out HPUX (well, version 11 at least) and shl_t is
+a pointer type so it's safe to use in the way it has been in
+dso_dl.c. On the other hand, HPUX11 support dlfcn too and
+according to their man page, prefer developers to move to that.
+I'll leave Richard's changes there as I guess dso_dl is needed
+for HPUX10.20.
+
+There is now a callback scheme in place where filename conversion can
+(a) be turned off altogether through the use of the
+ DSO_FLAG_NO_NAME_TRANSLATION flag,
+(b) be handled by default using the default DSO_METHOD's converter
+(c) overriden per-DSO by setting the override callback
+(d) a mix of (b) and (c) - eg. implement an override callback that;
+ (i) checks if we're win32 (if(strstr(dso->meth->name, "win32")....)
+ and if so, convert "blah" into "blah32.dll" (the default is
+ otherwise to make it "blah.dll").
+ (ii) default to the normal behaviour - we're not on win32, eg.
+ finish with (return dso->meth->dso_name_converter(dso,NULL)).
