Native mode
To run an old documents faster, and use the new features of
LATEX2e, you should try using <#570#> LATEX2e<#468#><#468#> native mode<#570#>.
This is done by replacing the command:
||<#470#>options<#470#>|,|<#471#>packages<#471#>|]|<#472#>class<#472#>
with:
|<#475#>options<#475#><#476#>class<#476#>
||
However, some documents which can be processed in LATEX~2.09
compatibility mode may not work in native mode. Some LATEX~2.09
packages will only work with LATEX2e<#479#><#479#> in 2.09 compatibility mode.
Some documents will cause errors because of LATEX2e's improved error
detection abilities.
But most LATEX~2.09 documents can be processed by LATEX2e<#480#><#480#>'s native
mode with the above change. Again, the easiest way to find out
whether your documents can be processed in native mode is to try it!
