Yes. The thing is that the scan script generates an initial set of 
tags for the files. The tags are actually generated by any /bin/tag/f*
script that is found. This is to save you the work of defining tags
that could be defined by a program. For example, I have used
the muid and permissions from the output of ls -l and the
name of elements in the full path name as the initial set of tags.

This is an example. This entry is for $home/src/9/block.c

/src/9/block.c muid=[nemo] perm=--rw-r--r-- usr nemo src 9 block.c

This would allow me to run "F 9 block" from acme. Other searches I do
are

F planb net slides
F tag sys src
F rwxrwxrwx sys
F os course slides


and the like. So far, I have not defined tags by hand. It seems that
in my case the names in the path suffice. But, for example, I added
the permissions as a tag soon after I started to use the program.
