Are open source license libraries acceptable?
Some are, many are not. Open source licenses often require redistribution or availability of source code, inclusion of license document with machine-executable redistribution, give the initial developer rights to licensee modifications, or need a lawyer to understand. These would be immediate disqualifications for many business, commercial, and consumer applications. Boost aims to avoid subjecting users to hard-to-comply-with license terms.
