License Compliance
All Clear
Training Builder uses only libraries and tools that are compatible with proprietary/commercial use. No licensing issues were found.
What This Means
- MPL-2.0 (mdBook): Any modifications to mdBook source code must be released under MPL-2.0. Using ideas/patterns from mdBook does not require license compliance.
- Apache 2.0 (HonKit): Requires attribution if distributing HonKit code. Using ideas/patterns does not require compliance.
- BSD (MkDocs, PyPDF2, ReportLab): Requires copyright notice retention in source/binary distributions.
- GPL-2.0 (Pandoc): Using pandoc as a command-line tool does not affect Training Builder's license. If we were to distribute pandoc or link to its code, GPL-2.0 would apply.
