The goal of the license is t o serve the eCos use r community as a who le. It allows all eCos us ers to develop
products wi thout paying anybod y anything, no mat ter how many develope rs are working o n the product or
how many units will be s hipped. The licens e also guarantees t hat the eCos source cod e will always be freel y
available. This a pplies not only to the co re eCos code itself b ut also to any changes tha t anybody makes to the
core. In part icular, it should preven t any company or individ ual contributin g code to the system an d then later
claiming that all eC os users are now guil ty of copyright or pat ent infringemen ts and have to pay royalti es. It
should also prevent any company from making some small improvements, calling the result a completely new
system, and re leasing this unde r a new and less generou s license.
The license does not requ ire users to rele ase the source code of any applicat ions that are developed w ith
