I link guile into apache, like you would assume if you extend
apache with guile, which is basically a library.

Apache has alot of handlers (17 i think), of which 10 are run
each time a request is handled. One of those 10 is the "content
handler", which provides the content for the requested object.

I translate a file into a function which duplicates the actions
that would be taken by (load "file.scm"). This is different from
modules, or i have misunderstood modules.

Apache config command i plan to add. Will add a reader for .tcl
files, e.g. Guile's Tcl reader, and have it handle .tcl files
cached like above.
