Class and package options

In LaTeX~2.09, only document styles could have options such as 22 or 23. In LaTeX2e<#108#><#108#>, both classes and packages are allowed to have options. For example, to specify a two-sided article with graphics using the 24 driver, you write: verbatim6 It is possible for packages to share common options. For example, you could, in addition, load the <#109#>color<#109#> package by specifying: verbatim7 But because 25 allows more than one package to be listed, this can be shortened to: verbatim8 In addition, packages will also use each option given to the 26 command (if they know what to do with it), so you could also write: verbatim9 Class and package options are covered in more detail in <#110#>The LaTeX Companion<#110#> and in <#111#>LaTeX2e for Class and Package Writers<#111#>.
