Dear Developers!
I've recently compiled NwChem 6.0 from sources for Cygwin to run it under i686 Win32 and
included Álvaro Vázquez-Mayagoitia 's "Generator of AIM Wavefunction files NWCHEM" there.
Is it legal now to place obtained .exe file to my homepage so that anyone could download it ?

Thank you in advance
