# HTML generation from the XML files in a nesdoc repository.
#
# The HTML files are placed in three directories:
# - ihtml: HTML files for interfaces
# - chtml: HTML (and support) files for components
# - index: HTML index files
#
# HTML files for configurations include a wiring graph. Graphviz version 1.10
# (and, hopefully, later versions) are supported.
#
# Only components and interfaces in "packages" (i.e., with a package prefix
# in their nicename attribute - see nesdoc-archive) are indexed - files
# from applications are skipped. However, these files are still present in
# the ihtml and chtml directories
