php_uusmerge -- Attempts a "Smart Merge" of parts that seem to belong to different files but which could belong to the same.
int php_uusmerge (int pass)
This function attempts a "Smart Merge" of parts that seem to belong to different files but which could belong to the same. Occasionally, you will find a posting with parts 1 to 3 and 5 to 8 of "picture.gif' and part 4 of "picture.gif". For human beings, it is obvious that these different parts belong to the same picture, to a machine, it is not. This function attempts to detect these conditions and merge the appropriate parts together. This function must be called repeatedly with increasing values for "pass". With pass == 0, only immediate fits are merged, increasing values allow greater "distances" between part numbers.
This function should only be called as last resort. The first call should be made with pass == 0, then with pass == 1 and at last with pass = 99.
