Usage
തിരുത്തുക|header=Identifiers (header text)
|addcats= allows adding a maintenance category. Usually checks a condition. Will only work in mainspace.
|addcats = {{#if:{{{OldParameter|}}}|[[Category:Bad parameter used]]}}
Testing a category
തിരുത്തുക|addcats_TEST=adds the category when not in mainspace (through the second parameter in {{main other}}). This is to test categorising in development (sandboxing). Such testpages (like in templatespace) would pollute formal maint categories, which is undesired. Solution: either use a dedicated spoiled category, or add the colon-trick[[:Category:..]].
