isarkeywords.el
 I am not sure what has changed here
nominal.thy
 includes a number of new lemmas (including freshness
and perm_aux things)
nominal_atoms.ML
 no particular changes here
nominal_permeq.ML
 a new version of the decision procedure using
for permutation composition the constant perm_aux
examples
 various adjustments

20060406 
urbanc 
20060406 
modified the perm_compose rule such that it
is applied as simplification rule (as simproc)
in the restricted case where the first
permutation is a swapping coming from a supports
problem
also deleted the perm_compose' rule from the set
of rules that are automatically tried

file  diff  annotate 
20060301 
urbanc 
20060301 
fixed a problem where a permutation is not analysed
when the term is of the form
(pi o f) x1...xn
This was the case because the head of this term is the
constant "nominal.perm". Now an applicability predicate
decides the right behaviour of the simproc

Changed Simplifier.simp_modifiers to Simplifier.simp_modifiers'.
This means the syntax of the tactics supports_simp and perm_simp
are exactly like simp, namely
(supports_simp add: .... del: ...)
where the add's and del's are optional.

Added (optional) arguments to the tactics
perm_eq_simp and supports_simp. They now
follow the "simp"way and use the syntax:
apply(supports_simp simp add: thms)
etc.
