| # Sed script that inserts the file called HEADER before the header entry. |
| # At each occurrence of a line starting with "msgid ", we execute the following |
| # commands. At the first occurrence, insert the file. At the following |
| # occurrences, do nothing. The distinction between the first and the following |
| # occurrences is achieved by looking at the hold space. |
| # Test if the hold space is empty. |
| # Yes it was empty. First occurrence. Read the file. |
| # Output the file's contents by reading the next line. But don't lose the |
| # current line while doing this. |
| # The hold space was nonempty. Following occurrences. Do nothing. |
