[texhax] Help with footnotes

[Michael Barr]

Can someone suggest a good macro package for flexible footnotes?  I have 
translated a long article that has many chapters and many footnotes.  I 
need a second set of footnotes for translators notes, which I will number 
alphabetically.  I have done that, using something of a kludge, but two 
problems remain.  First the book style starts the footnote numbering over 
for each chapter.  The original didn't and I wish to preserve his 
numbering.  Secondly, he has one footnote numbered 2bis; it appears, of 
course between 2 and 3.  Does any package give that much flexibility?  If 
not, I may have to use plain's footnotes.
