96 } 1.3 COntent Oriented LaTeX (COOL) \Style \Style{ options } sets the style of the output (how to notate particular func- tions). options is a comma delimited list of the form key = value , where key is the long form of the command name without the preceeding backslash (i.e. Integrate and not Int or \Int). The list can be in any order and need only contain the styles that the user desires to set. There can be multiple \Style commands within any document―the styled output of the command depends on the last \Style command to have speci?ed its style. For a list of styling options for a command, see the code where the command is de?ned
