Softwares (não) Impostos no Equador; Software Livre no IRPF2007

Enquanto isso, no Equador...  (veja e-mail da equinux abaixo)

JÃ¡ que o governo deles libera a especificaÃ§Ã£o dos formatos de arquivo,
ainda que ofereÃ§a um programa apenas para MS-Windows, eles vÃ£o e
implementam o deles, livre.

Lindo, nÃ©?

Falar em licenÃ§a, sabe o que descobri hoje no programa IRPF2007 versÃ£o
Java, enquanto preparava as fotos no topo da minha home page (URL na
assinatura)?  Diversas licenÃ§as de Software Livre, algumas bem escondidas!

% unzip -q irpf2007v1.0.zip -d irpf2007
% cd irpf2007
% unzip -q IRPF.jar -d IRPF 
replace IRPF/build.properties? [y]es, [n]o, [A]ll, [N]one, [r]ename: A
% cd IRPF
% cat license.txt

Legal, nÃ©?  Bem que gostam que respeitem as liberdades deles, mas nada
de respeitar as nossas :-(

Pelo menos nÃ£o estÃ£o violando nenhuma dessas licenÃ§as.

Agora...

% cd ..

                  GNU LESSER GENERAL PUBLIC LICENSE
                       Version 2.1, February 1999
[...]
  4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
[...]
  6. As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.

  You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License.  You must supply a copy of this License.  If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License.  Also, you must do one
of these things:

    a) Accompany the work with the complete corresponding
    machine-readable source code for the Library including whatever
    changes were used in the work (which must be distributed under
    Sections 1 and 2 above); and, if the work is an executable linked
    with the Library, with the complete machine-readable "work that
    uses the Library", as object code and/or source code, so that the
    user can modify the Library and then relink to produce a modified
    Library will not necessarily be able to recompile the application
    to use the modified definitions.)

    b) Use a suitable shared library mechanism for linking with the
    Library.  A suitable mechanism is one that (1) uses at run time a
    copy of the library already present on the user's computer system,
    rather than copying library functions into the executable, and (2)
    will operate properly with a modified version of the library, if
    the user installs one, as long as the modified version is
    interface-compatible with the version that the work was made with.

    c) Accompany the work with a written offer, valid for at
    least three years, to give the same user the materials
    specified in Subsection 6a, above, for a charge no more
    than the cost of performing this distribution.

    d) If distribution of the work is made by offering access to copy
    from a designated place, offer equivalent access to copy the above
    specified materials from the same place.

    e) Verify that the user has already received a copy of these
    materials or that you have already sent this user a copy.

Hmm...  Interessante...  NÃ£o vejo o cÃ³digo fonte sob a LGPL em lugar
nenhum.  SerÃ¡ que a SRF estÃ¡ nos fazendo o favor de violar a LGPL?
