gdb: Free Software

 
 Free Software
 =============
 
 GDB is "free software", protected by the GNU General Public License
 (GPL). The GPL gives you the freedom to copy or adapt a licensed
 program--but every person getting a copy also gets with it the freedom
 to modify that copy (which means that they must get access to the source
 code), and the freedom to distribute further copies.  Typical software
 companies use copyrights to limit your freedoms; the Free Software
 Foundation uses the GPL to preserve these freedoms.
 
    Fundamentally, the General Public License is a license which says
 that you have these freedoms and that you cannot take these freedoms
 away from anyone else.
