Texpad on OS X is scriptable. That is to say you can add other programs that do clever but non-standard things to Texpad in a way that it let’s them fit into its workflow.
.tpbuild scripts are examples of such utilities. Their use is described in section 2.3.3 of Texpad Guide, accessible from the Help menu in the app or downloadable here.
Out-of-the-box, Texpad comes with a number of these scripts. More of these scripts can be downloaded from our TexpadKB repository:

Some of these scripts were suggested and written by users to share with other Texpad users. If you don’t find a script you’re looking for here, please be in touch with us at support@vallettaventures.com.
