#
|

|
|
# BML rendering for Plack via DW::Request. This module implements the BML
|
||
|
|
# handler logic using the DW::Request abstraction layer instead of Apache APIs,
|
||
|
|
# allowing BML pages to render under Plack.
|
||
|
|
#
|
||
|
|
# The existing Apache::BML module continues to work unchanged for mod_perl.
|
||
|
|
# This module reuses the core BML engine (bml_decode, bml_block, config loading,
|
||
|
|
# scheme/look system) and only replaces the handler and request adapter layers.
