Activate a Project

Before typesetting, you must generally tell iTeXMac what kind of action it must perform. This is done by activating a project, either a generic one or a customized one of your own.

Select a project in the activate TeX submenu.
You can tell iTeXMac what project to activate by inserting the line

"%! iTeXMac(project): your project path".

in the very header of your input file, see Typesetting Control from the source.
