#####
##### tde_create_l10n_template
#####
##### Macro is used to generate a translation template - POT file.
#####
##### Syntax:
##### tde_create_l10n_template(
##### CATALOG file_name
##### [SOURCES source_spec [source_spec]]
##### [KEYWORDS keyword [keyword]]
##### [ATTRIBUTES attrib_spec [attrib_spec]]
##### [DESTINATION directory]
##### )
#####
##### Where:
##### CATALOG determines the target file name (without pot suffix).
##### SOURCES can be specified by several options:
##### a) Do not specify anything
##### - all usual source files will be automatically searched.
##### b) Enter the directory name - for example, '.' or 'src'
##### - all the usual source files in the specified directory
##### and subdirectories will be searched.
##### c) Enter the mask - for example '*.cpp'
##### - all files with the specified mask will be searched.
##### d) Specify the name of the individual file.
##### The methods from b) to d) can be combined.
##### KEYWORDS determines additional keywords for xgettext.
##### ATTRIBUTES determines files and specification for extractattr:
##### source_spec:element,attribute[,context]
##### DESTINATION determines directory to save translation template.
