This is the perl script 'makefsdata' converted to a plain C console application
|
||||
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, htmlgen will attempt to
|
||||
process files in subdirectory 'fs'.
