Is this license OK for main?
I think so, but I like to read, if anyone has objections:
Permission is granted to make and distribute verbatim copies of
this software provided the copyright notice and this permission
notice are preserved on all copies.
Permission is granted to copy and distribute modified versions
of this software under the conditions for verbatim copying,
provided that the entire resulting derived work is distributed
under the terms of a permission notice identical to this one.
Permission is granted to copy and distribute translations of
this software into another language, under the above conditions
for modified versions, except that this permission notice may be
stated in a translation approved by the author.
The last sentence may be a problem?
