I see. I wonder if it would even be possible to merge common dependency subtrees in this form of ascii report.=20 However, if the script supported graphviz (.dot) output it would be perhaps feasible. The merging perhaps could even happen automatically within graphviz. Please look at the sample graphics I've prepared with graphviz: http://admin.sibptus.ru/~vas/t.png I did not do any special common dependency processing, graphviz merged the "expat" dependencies for me. Anyway, even in this form the utility could be useful to me, thank you for pointing it out to me. --=20 Victor Sudakov, VAS4-RIPE, VAS47-RIPN 2:5005/49@fidonet http://vas.tomsk.ru/ --IS0zKkzwUGydFO0o Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEcBAEBAgAGBQJcNIhrAAoJEA2k8lmbXsY0zvMH/0CUsUJ0kxzD3MaV/ka6nkIc vNCi9YFZiMYYJeWpZd5++5ZJBg8WKrUzHZ1wBkoibuHDsOtbWz8W+TkPOeyF/MuA oqwXdr2jbjKP1bT4pHi9IcOyavwadjnYegtdmxO5UUx7/Yxr+JXyhqZcLNFmkOb2 32freWN8B96dF4eFvw3GZmNVTUpzge4Ky6PcXC9crY6FCFSqd4txZHr0Nl4LoIht Oi/pykLRcB7y+NXzC2f/Jv/AyY9eyHq4IZxpZlanFedz7mEcvEeWZkfdP6BPfLu3 FhwEt9GgMkzDGv6yQlBIPvtuvEQu7VmjciPKUR0Ec2v1F3avfD11vvS4tCkV2I4= =Wtfn -----END PGP SIGNATURE----- --IS0zKkzwUGydFO0o--
