readable source code, which must be distributed under the
terms of Sections 1 and 2 above on a medium customarily used
for software interchange; or,
b) Accompany it with a written oer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to
be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange; or,
c) Accompany it with the information you received as to the
oer to distribute corresponding source code. (This alternative
is allowed only for noncommercial distribution and only if you
received the program in object code or executable form with
such an oer, in accord with Subsection b above.)
The source code for a work means the preferred form of
the work for making modications to it. For an executable
work, complete source code means all the source code for all
modules it contains, plus any associated interface denition
les, plus the scripts used to control compilation and
installation of the executable. However, as a special exception,
the source code distributed need not include anything that
is normally distributed (in either source or binary form) with
the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that
component itself accompanies the executable.
If distribution of executable or object code is made by
oering access to copy from a designated place, then oering
equivalent access to copy the source code from the same place
counts as distribution of the source code, even though third
parties are not compelled to copy the source along with the
object code.
