This directory contains a script ('makefsdata') to create C code suitable for
|
||||
httpd for given html pages (or other files) in a directory.
|
||||
|
||||
There is also a plain C console application doing the same and extended a bit.
|
||||
|
||||
Usage: htmlgen [targetdir] [-s] [-i]s
|
||||
targetdir: relative or absolute path to files to convert
|
||||
switch -s: toggle processing of subdirectories (default is on)
|
||||
switch -e: exclude HTTP header from file (header is created at runtime, default is on)
|
||||
switch -11: include HTTP 1.1 header (1.0 is default)
|
||||
|
||||
if targetdir not specified, makefsdata will attempt to
|
||||
process files in subdirectory 'fs'.
