X-Git-Tag: make_still_working~4040
X-Git-Url: http://matita.cs.unibo.it/gitweb/?a=commitdiff_plain;h=f524a0d716de2bdc0874aace8f82f6289034eccf;p=helm.git

cicNotationUtil: in fresh_name_generator, "\eta" replaced with "eta", which is an identifier
cicNotationPp: debug mode turned off
logic/cprop_connectives.ma: duplicate lines removed
matitaScript: missing "\n\n" added in front of inline output
core_notation.moo: the "default" notation directive has a bug. Commented out.
