StAc is very modular and intend to keep it that way. Here are its main components right now:

( TODO: description of the role of the Worker, most important component, needs to be written ).

Task	Implementation	Comment
UI	Curses::Application, Getopt::Long
Local Storage (Stac's data)	XML::LibXML, XML::PatAction
Remote Storage (Tools)	Cvs
Caching	Cache::Cache
Logging	Log::Log4perl	Retire your debugger, log smartly...
Internationalization	Locale::Maketext, I18N::LangTags
Exception handling	Exception::Class
Templating	Templating Toolkit
Fuzzy matching	String::Similarity	will be used for project name matching (code written, but disabled for now)
Config file format	Config::ApacheFormat	XML is another possible implementation, but apache format is more human readable (less clutter) and known to almost all sys-admins

for detailed dependencies on other perl modules(classes/frameworks) and versions needed, see StAcMakefile.
