# info about data structure
# it is a hash, keys introduce perl-like structure items:
#	'dict'		... hash; key is the primary locale for the given dictioanry, e.g. "en_US"
#			    the value is hash that store an information about ech dictionary using
#			    tags; the known tags are:
#	    'language'		hash(*) of string; language name, e.g Catalan, German, Norwegian Bokmaal
#	    'pack_suffix'	hash(*) of string; package name is normaly defined by the language name (lowercase,
#				underscore instread of space); you might define a non-standard one
#				using this tag, e.g norsk-bokmaal for Norwegian Bokmaal
#	    'prov_lang'		hash(*) of string; most dictionaries provides the language defined by the locale;
#				you might force the full locale using this tag; just mention
#				the full locale here again, e.g. de_DE vs de_AT
#	    'version'		hash(*) of string; package version, e.g. 2.1.5
#	    'source'		hash(*) of string; source file name, e.g. catalan.oxt
#	    'source_number'	hash(*) of integers; number of the source file, e.g. 1000, 1001, 1002
#	    'license'		hash(*) of array of strings; comma separated list of dictionary licenses, e.g. GPLv2, LGPLv2.1
#	    'types'		hash(*) of array of strings; comma separated list of included dictionary types; possible values are:
#				myspell, hunspell, hyphen, thesaurus
#	    'url'		hash(*) of string; url where the dictionary sources was taken from, e.g.
#				http://extensions.services.openoffice.org/project/dict-catalan
#	    'encoding'		hash(*) of string; documentation files in non-UTF-8 enconding should be recoded; the original
#				encoding is guessed from the locale; you might define another encoding
#				here, e.g. ISO-8859-1 
#	    'depdendency'	hash(*) of array of strings; extra dependency, e,g. Conflicts:      myspell-german-old
#	    'prep'		hash(*) of array of strings; extra hacks for the %prep section
#
#	    		    the above tags are taken from the data file; the hash also support some extra keys:
#	    'contition_dict'    string; defines a condition under which the dictionary is packaged, e.g. %if %suse_version <= 1120
#	'license'	... hash; key is the license used for a dictionary, e.g. LGPLv2; it is used to generate
#				licenses for the source package

#
# hash(*) of ...   - key is the condition under which the tag is defined; it is usually used to define a special tag
#		     for another distro; the key 'default' defines tags for the default distro, ...
