## #nuweb - Server-side HTTP scripting library for BASH
##
## *nuweb* is set of BASH function to ease implementation of CGI scripts using
## BASH. Idea behind it, is to allow for reuse of existing shell scripts
## and command-line utilities, without need to duplicate functionality.
##
## *nuweb* is based on *nux-env*, which allows large code-share with *nux-env*
## command line tools and use of *nux-env* libraries.
##
## *nuweb* is separated into several components:
##
## nuweb::
## this library, base functionality
## nuweb/router:: router support functionality - dispatch of code
## based on path and query parameters
## nuweb/html::
## basic support for generating HTML content
