There are two graphics packages:
- <#935#><#140#>graphics<#140#><#935#>
- The `standard' graphics package.
- <#936#><#141#>graphicx<#141#><#936#>
- The `extended' or `enhanced' graphics
package.
The two differ only in the format of optional arguments for the
commands defined. The command names, and the mandatory arguments are
the same for the two packages.
