1 Before marking strings as internationalizable, substitutions of
1 variables into the string need to be converted to ‘format’ applications.
1 For example, ‘"file $filename not found"’ becomes ‘[format "file %s not
1 found" $filename]’. Only after this is done, can the strings be marked
1 and extracted. After marking, this example becomes ‘[format [_ "file %s
1 not found"] $filename]’ or ‘[msgcat::mc "file %s not found" $filename]’.
1 Note that the ‘msgcat::mc’ function implicitly calls ‘format’ when more
1 than one argument is given.
