if.you.want.it,.that.you.can.change.the.software.
or. use. pieces. of. it. in. new. free. programs;. and.
that.you.know.you.can.do.these.things.
..To.protect.your.rights,.we.need.to.make.re-
strictions.that.forbid.anyone.to.deny.you.these.
rights.or.to.ask.you.to.surrender.the.rights.
These. restrictions. translate. to. certain. respon-
sibilities. for. you. if. you. distribute. copies. of. the.

..For.example,.if.you.distribute.copies.of.such.a.

stantly.by.software.patents...We.wish.to.avoid.
the.danger.that.redistributors.of.a.free.program.
will.individually.obtain.patent.licenses,.in.effect.

this,. we. have. made. it. clear. that. any. patent.
