IMPLEMENTATION: Package options 123simpler than testing whether the <strong>package</strong> was loaded both in the preamble as wellas at the beginning of the document (which is what one would have to do).Package authors should check whether the command is already defined so thatexisting definitions by other <strong>package</strong>s aren’t overwritten. Example:\def\MinionPro@MT@Hook{\DeclareMicrotypeAlias{MinionPro-LF}{MinionPro}}\@if<strong>package</strong>loaded{<strong>microtype</strong>}\MinionPro@MT@Hook{\@ifundefined{Microtype@Hook}{\let\Microtype@Hook\MinionPro@MT@Hook}{\g@addto@macro\Microtype@Hook{\MinionPro@MT@Hook}}}\MicroType@Hook with a capital T (which only existed in version 1.7) is providedfor compatibility reasons. At some point in the future, it will no longer be available,hence it should not be used.3998 \MT@ifdefined@c@T\MicroType@Hook{\MT@warning{%3999 Command \string\MicroType@Hook\space is deprecated.\MessageBreak4000 Use \string\Microtype@Hook\space instead}\MicroType@Hook}4001 \MT@ifdefined@c@T\Microtype@Hook\Microtype@Hook\<strong>microtype</strong>setup\MT@define@optionX14.4.5 Changing options laterInside the preamble, \<strong>microtype</strong>setup accepts the same options as the <strong>package</strong> (unlessdefersetup=false). In the document body, it accepts the options: protrusion,expansion, activate, tracking, spacing and kerning.
