The module should preferably not be called directly from templates or other modules.
To use it from a template, use <code>{{[[Template:entryname|entryname]]}}</code>.
Within a module, use [[Module:languages#Language:makeEntryName]].

For testcases, see [[Module:]=] .. title_without_namespace:gsub("/documentation$", "") .. [=[/testcases]].

== Functions ==
; <code>makeEntryName(text, lang, sc)</code>
: Generates an entry name for a given piece of <code>text</code> written in the script specified by the code <code>sc</code>, and language specified by the code <code>lang</code>.
: When entry name generation fails, returns <code>nil</code>.]=]
