am­sthm – Type­set­ting the­o­rems (AMS style)

The pack­age fa­cil­i­tates the kind of the­o­rem setup typ­i­cally needed in Amer­i­can Math­e­mat­i­cal So­ci­ety pub­li­ca­tions. The pack­age of­fers the the­o­rem setup of the AMS doc­u­ment classes (am­sart, ams­book, etc.) en­cap­su­lated in LaTeX pack­age form so that it can be used with other doc­u­ment classes.
Am­sthm is part of the (re­quired) AMS-LaTeX dis­tri­bu­tion, so should be present in any LaTeX dis­tri­bu­tion.
