@title[#:tag "c-mods"]{Embedding Scheme Modules via C}

The @DFlag{c-mods} mode for @|mzc| takes a set of Scheme modules and
generates a C source file that can be used as part of program that
embeds the PLT Scheme run-time system. See @secref[#:doc inside-doc
"embedding"] in @other-manual[inside-doc] for an explanation of
embedding programs.

The generated source file embeds the specified modules, and it defines
a @tt{declare_modules} function that puts the module declarations
into a namespace. Thus, using the output of @exec{mzc --c-mods}, a
program can embed PLT Scheme with a set of modules so that it does not
need a @filepath{collects} directory to load modules at run time.
