in­put­trc – Trace which file loads which

The pack­age pro­duces screen/log mes­sages of the form ‘<cur­rent> INPUTTING <next>’ re­port­ing LaTeX in­put com­mands (<cur­rent> and <next> be­ing file names). The mes­sage is in­dented to re­flect the level of in­put nest­ing.
Trac­ing may be turned on and off, and the unit of in­den­ta­tion may be ad­justed.
The im­ple­men­ta­tion some­what re­sem­bles those of pack­ages FiNK and in­put­file.
