If you can't find the answer for your problem here, try looking in
<#626#>LaTeX: A Document Preparation System<#626#> or <#627#>The LaTeX Companion<#627#>. If you have a problem with
installing LaTeX, look in the installation guide files which come with
the distribution.
If this doesn't help, contact your local LaTeX<#628#><#628#> guru or local
LaTeX<#629#><#629#> mailing list.
If you think you've discovered a bug then please report it! First,
you should find out if the problem is with a third-party package or
class. If the problem is caused by a package or class other than
those listed in Section~#Secclasspackages#630> then please report
the problem to the author of the package or class, not to the LaTeX3
project team.
If the bug really is with core LaTeX<#631#><#631#> then you should create a
<#632#>short<#632#>, <#633#>self-contained<#633#> document which exhibits the
problem. You should run a <#634#>recent<#634#> (less than a year old)
version of LaTeX<#635#><#635#> on the file and then run LaTeX<#636#><#636#> on
416. This will create an error report which you should
send, together with the sample document and log file, to the
LaTeX<#637#><#637#> bugs address which can be found in the file
417 or 418.
