+.SH LOCAL QUIRKS
+This section describes how non-vendor software works at EBI.  Chances
+are that other sites will work differently.  This description is here as
+an example setup for \*(sw.
+.PP
+All the non-vendor software gets put in one big shared filesystem, and
+is exported from our main fileserver.  The filesystem is mounted on all
+clients as
+.BR /sw/common .
+Architecture-neutral files are then
+placed in the conventional subdirectories off
+.B /sw/common
+(e.g., 
+.BR /sw/common/share,
+or 
+.BR /sw/common/info ).
+Architecture specific files are stored in subdirectories off
+.BR /sw/common/arch .
+For example, Linux binaries go in
+.BR /sw/common/arch/i386-linux/bin ,
+and Solaris libraries in
+.BR /sw/common/arch/sparc-solaris/lib .
+Additionally, each architecture-specific subtree has a symbolic link
+back up to
+.B /sw/common
+for each of the architecture-neutral subdirectories.
+.PP
+There is a symbolic link on every client, from
+.B /sw/arch
+to
+.BI /sw/common/arch/ arch\fR,
+where
+.I arch
+is the architecture of that client.  Thus, every client has two
+.I views
+of the software repository: the `common' view where every host sees
+exactly the same mapping between filenames and files, and the `arch'
+view where every host sees the same mapping between filenames and
+programs which do the same job.
+.PP
+And that's just about it.
