@< @b(LISPM) - Standard LISP machine type. @cr
@sp 1

All MIT-type LISP machines -- Lambdas, CADRs, Explorers, and Symbolics --
are defined as ``LISPM,LISPM'' in Lambda site files.
For proper pathname parsing,
Symbolics hosts must be given a file-system type of ``LMFS'' in the 
@l(:SPECIAL-FILE-HOSTS) site option.

@< @b(UNIX) - ``Standard'' Unix host/file-system type. @cr
@sp 1

This host and file-system type provides a compromise
subset of functionality common to most Unix implementations.
This means that some modern Unix naming extensions are not implemented.
@sp 1
For example, Apollo pathnames cannot be constructed with references
to other nodes on the network.
@sp 1
Also, the standard Unix directory line parser may not function with some
remote hosts.
While most Unix FTP servers provide a ``standard'' listing from the command @l(ls -l),
some do not.
The @l(:UNIX-SGI) file-system type is provided to accomodate a known exception,
Silicon Graphics Unix systems.

@< @b(VMS) - DEC VAX/VMS host type. @cr
@sp 1

VMS pathname handling handles version 4 naming conventions.
No length limitations are imposed, to handle any future expansion by DEC.
Developers should take care to transform filenames, since
many characters permitted by the Lambda will not be acceptable to VMS.
