extractattr [flags] filenames
This script extracts element attributes from designer (.ui) and XMLGIU (.rc) files
and writes on standard output (usually redirected to rc.cpp) the equivalent
i18n() calls so that xgettext can parse them.
--attr=spec : Specify the attribute to be extracted. The specification
consists of the following comma separated arguments:
Element,attribute[,context]
The context is optional and overrides the name set by
--context below. Repeat the flag to specify multiple
attributes:
--attr=Title,data --attr=Description,data,Stencils
--context=name : Give i18n calls a context name: i18n("name", ...)
--lines : Include source line numbers in comments (deprecated, it is switched on by default now)
--help|? : Display this summary
