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#>.
