Hi Tibor,
You could change the order of the lines without problems; you can also add lines without issues.
If you'd add a line to the file which already is in there, the last line will take precedence.
If you'd like to check whether a file is still valid (because of syntax errors or the like) you can check it as follows:
# perl -cw sk_SK.pm
sk_SK.pm syntax OK
If your file contains syntax errors you'd see line numbers that indicate where the problem is. You could use text editors with syntax highlighting (such as Notepad Plus Plus on Windows) to aid in this too.
If you'd like to complete or update the sk_SK translation that would be great, please submit your changes to the i18n mailing list. If you'd want to make customizations to the file, such as wording specifically for your company or the like, please create a custom translation file for that, it will make any future upgrades a lot easier.
