When building FreeBSD the makefiles invoke find with various flags such as
`-s` that aren't supported in the native /usr/bin/find. To fix this I
build the FreeBSD version of find and use that when crossbuilding.
Inserting lots if #ifdefs in the code is rather ugly but I don't see a
better solution.

Mainly focus on files that use BSD 3-Clause license.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

If -ignore_readdir_race is present, [ENOENT] errors caused by deleting a
file after find has read its name from a directory are ignored.
Formerly, -ignore_readdir_race did nothing.

in our find.
The following are nops because they aren't relevant to our find:
-ignore_readdir_race
-noignore_readdir_race
-noleaf
The following aliaes were created:
-gid -> -group [2]
-uid -> -user [2]
-wholename -> -path
-iwholename -> ipath
-mount -> -xdev
-d -> -depth [1]
The following new primaries were created:
-lname like -name, but matches symbolic links only)
-ilname like -lname but case insensitive
-quit exit(0)
-samefile returns true for hard links to the specified file
-true Always true
I changed one primary to match GNU find since I think our use of it violates
POLA
-false Always false (was an alias for -not!)
Also, document the '+' modifier for -execdir, as well as all of the above.
This was previously implemented.
Document the remaining 7 primaries that are in GNU find, but aren't yet
implemented in find(1)
[1] This was done in GNU find for compatibility with FreeBSD, yet they
mixed up command line args and primary args.
[2] -uid/-gid in GNU find ONLY takes a numeric arg, but that arg does the
normal range thing that. GNU find -user and -uid also take a numberic arg,
but don't do the range processing. find(1) does both for -user and -group,
so making -uid and -gid aliases is compatible for all non-error cases used
in GNU find. While not perfect emulation, this seems a reasonable thing
for us.
Note to self: if a comment says a list must be lexically sorted, sort
the list lexically.

have it so that it can be used in conjunction with
"-exec setfacl {} \;" (to find(1)), among others.

With it, you can form queries like

As an extra bonus, the program is ANSI-fied - the original version
relies on some obscure features of K&R C.

-E Interpret regular expressions followed by -regex and -iregex op-
tions as extended (modern) regular expressions rather than basic
regular expressions (BRE's). The re_format(7) manual page fully
describes both formats.
-iname pattern
Like -name, but the match is case insensitive.
-ipath pattern
Like -path, but the match is case insensitive.
-regex pattern
True if the whole path of the file matches pattern using regular
expression. To match a file named ``./foo/xyzzy'', you can use
the regular expression ``.*/[xyz]*'' or ``.*/foo/.*'', but not
``xyzzy'' or ``/foo/''.
-iregex pattern
Like -regex, but the match is case insensitive.
These are meant to be compatible with other find(1) implementations
such as GNU's or NetBSD's except regexp library differences.

doesn't know about getvfsbyname() and the vfsconf structure. This
disables the -fstype option if compiled with a pre-processor that
defines __NetBSD__. With the FreeBSD built pre-processor, find can only
be built with the FreeBSD libc. So when running with a NetBSD kernel,
FreeBSD's libc will have to return ENOSYS for things that NetBSD
doesn't support. That's life in a hybrid world.

goes to a fair degree of trouble to enable something like this to
be safe: cd /tmp && find . -mtime +7 -delete
It removes both files and directories. It does not attempt to remove
immutable files (an earlier version I showed to a few people did a chflags
and tried to blow away even immutable files. Too risky..)
It is thought to be safe because it forces the fts(3) driven descent to
only do "minimal risk" stuff. specifically, -follow is disabled, it does
checking to see that it chdir'ed to the directory it thought it was
going to, it will *not* pass a pathname with a '/' character in it to
unlink(), so it should be totally immune to symlink tree races. If it runs
into something "fishy", it bails out rather than blunder ahead.. It's better
to do that if somebody is trying to compromise security rather than risk
giving them an opportunity. Since the unlink()/rmdir() is being called
from within the current working directory during the tree descent, there
are no fork/exec overheads or races.
As a side effect of this paranoia, you cannot do a
"find /somewhere/dir -delete", as the last argument to rmdir() is
"/somewhere/dir", and the checking won't allow it. Besides, one would use
rm -rf for that case anyway. :-)
