CHANGES (p.hol2dk.2.1.0.doc.CHANGES)

command nbp to print the number of (useful) proofs
command files to print theorem statements following the file structuration in HOL-Light
command thms to print theorems (named or not) proved in a file
command unsplit to put the proofs of all the theorems proved in a HOL-Light file in the same Lambdapi file
command concl to print the statements of theorems between two indexes
option --max-dup $k to share the proof of a theorem if it is duplicated more than $k times
renamings to handle the Multivariate library
test/Sig_mappings_N.v and test/Sig_With_N.v: axiomatizations of mappings_N.v and With_N.v respectively
test/Makefile: generates Spec_mappings_N.v and Spec_With_N.v, standalone versions of Sig_mappings_N.v and Sig_With_N.v, and checks the correctness of mappings_N.v and With_N.v wrt to those specification files the use of Spec_With_N.v instead of With_N.v allows to reduce the Coq checking time of Multivariate/make_complex.ml by 40% (21 hours instead of 35 hours)

Big improvements in Lambdapi and Coq file generation time, and Coq checking time.

hol2dk can now generate term abbreviations and proofs in several files in parallel:
- The option --max-size-abbrev allows to fix the maximum size for term abbreviations files.
- The option --max-size-proof allows to fix the maximum size for proof files.
optimization of lp file dependencies in generated lp files.
generation of Makefile lpo dependencies at the same time as lp files.
Makefile: lpo and vo dependencies are recomputed automatically.

FILES_WITH_SHARING renamed into BIG_FILES and not added by add-links anymore
command dump[-simp]-use renamed into dump[-simp]-before-hol
for each theorem, two files are generated: one with the proof, and one declaring the theorem as an axiom

add-links script
command rewrite to simplify prf files
command purge to compute useless theorems these two commands greatly reduce the size of generated proofs
command simp is equivalent to rewrite and purge
command dump-simp is equivalent to dump, pos, use and simp
allow simultaneous dumping
alignments of the types option, Sum, list, char, nadd
command split to generate a pos/use/sti/nbp file for each named theorem (an sti file contains the starting index of the corresponding proof)
command theorem to generate the lp files corresponding to a named theorem
Makefile to generate and check lp and coq files generated with split
command size to get statistics on the size of terms
option --print-stats to print statistics on hash tables at exit
use hash tables instead of maps to build abbreviations maps
use sharing when building canonical types and terms
add option --use-sharing for using sharing in lp output when defining term abbreviations
command nbp to get the number of proof steps
commands patch, unpatch and link to call the corresponding scripts
command env to print $HOL2DK_DIR and $HOLLIGHT_DIR

First release.
