doc­strip – Re­move com­ments from file

The pack­age pre­pares a LaTeX ker­nel or pack­age source file for ac­tual use, by re­mov­ing the doc­u­men­ta­tion and meta-data. The pack­age can con­di­tion­ally in­clude parts of the source file, gen­er­ate many files from a sin­gle source, and gen­er­ate a sin­gle out­put from sev­eral source files.
The pack­age is part of the LaTeX dis­tri­bu­tion.
