NAME
Text::Amuse::Preprocessor::Footnotes - Rearrange footnote numbering in muse docs
DESCRIPTION
Given an input file, scan its footnotes and rearrange them. This means that such document:
#title test
Hello [1] There [1] Test [1]
[1] first
Hello hello
[1] second
[1] thirdwill become
#title test
Hello [1] There [2] Test [3]
Hello hello
[1] first
[2] second
[3] thirdGiven that the effects of the rearranging could be very destructive and mess up your documents, the module try to play on the safe side and will refuse to write out a file if there is a count mismatch between the footnotes and the number of references in the body.
The core concept is that the module doesn't care about the number. Only order matters.
This could be tricky if the document uses the number between square brackets for other than footnotes.
Also used internally by Text::Amuse::Preprocessor.
