"""Grep warnings messages and output HTML tables or warning counts in CSV.
Default is to output warnings in HTML tables grouped by warning severity.
Use option --byproject to output tables grouped by source file projects.
Use option --gencsv to output warning counts in CSV format.
# List of important data structures and functions in this script.
# To parse and keep warning message in the input file:
# severity: classification of message severity
# severity.range [0, 1, ... last_severity_level]
# severity.colors for header background
# severity.column_headers for the warning count table
# severity.headers for warning message tables
# warn_patterns:
# warn_patterns[w]['category'] tool that issued the warning, not used now
# warn_patterns[w]['description'] table heading
# warn_patterns[w]['members'] matched warnings from input
# warn_patterns[w]['option'] compiler flag to control the warning
# warn_patterns[w]['patterns'] regular expressions to match warnings
# warn_patterns[w]['projects'][p] number of warnings of pattern w in p
# warn_patterns[w]['severity'] severity level
# project_list[p][0] project name
# project_list[p][1] regular expression to match a project path
# project_patterns[p] re.compile(project_list[p][1])
# project_names[p] project_list[p][0]
# warning_messages array of each warning message, without source url
# warning_records array of [idx to warn_patterns,
# idx to project_names,
# idx to warning_messages]
# android_root
# platform_version
# target_product
