+=head1 NAME
+
+find2perl - translate find command lines to Perl code
+
+=head1 SYNOPSIS
+
+ find2perl [paths] [predicates] | perl
+
+=head1 DESCRIPTION
+
+find2perl is a little translator to convert find command lines to
+equivalent Perl code. The resulting code is typically faster than
+running find itself.
+
+"paths" are a set of paths where find2perl will start its searches and
+"predicates" are taken from the following list.
+
+=over 4
+
+=item C<! PREDICATE>
+
+Negate the sense of the following predicate. The C<!> must be passed as
+a distinct argument, so it may need to be surrounded by whitespace and/or
+quoted from interpretation by the shell using a backslash (just as with
+using C<find(1)>).
+
+=item C<( PREDICATES )>
+
+Group the given PREDICATES. The parentheses must be passed as distinct
+arguments, so they may need to be surrounded by whitespace and/or
+quoted from interpretation by the shell using a backslash (just as with
+using C<find(1)>).
+
+=item C<PREDICATE1 PREDICATE2>
+
+True if _both_ PREDICATE1 and PREDICATE2 are true; PREDICATE2 is not
+evaluated if PREDICATE1 is false.
+
+=item C<PREDICATE1 -o PREDICATE2>
+
+True if either one of PREDICATE1 or PREDICATE2 is true; PREDICATE2 is
+not evaluated if PREDICATE1 is true.
+
+=item C<-follow>
+
+Follow (dereference) symlinks. [XXX doesn't work fully, see L<BUGS>]
+
+=item C<-depth>
+
+Change directory traversal algorithm from breadth-first to depth-first.
+
+=item C<-prune>
+
+Do not descend into the directory currently matched.
+
+=item C<-xdev>
+
+Do not traverse mount points (prunes search at mount-point directories).
+
+=item C<-name GLOB>
+
+File name matches specified GLOB wildcard pattern. GLOB may need to be
+quoted to avoid interpretation by the shell (just as with using
+C<find(1)>).
+
+=item C<-perm PERM>
+
+Low-order 9 bits of permission match octal value PERM.
+
+=item C<-perm -PERM>
+
+The bits specified in PERM are all set in file's permissions.
+
+=item C<-type X>
+
+The file's type matches perl's C<-X> operator.
+
+=item C<-fstype TYPE>
+
+Filesystem of current path is of type TYPE (only NFS/non-NFS distinction
+is implemented).
+
+=item C<-user USER>
+
+True if USER is owner of file.
+
+=item C<-group GROUP>
+
+True if file's group is GROUP.
+
+=item C<-nouser>
+
+True if file's owner is not in password database.
+
+=item C<-nogroup>
+
+True if file's group is not in group database.
+
+=item C<-inum INUM>
+
+True file's inode number is INUM.
+
+=item C<-links N>
+
+True if (hard) link count of file matches N (see below).
+
+=item C<-size N>
+
+True if file's size matches N (see below) N is normally counted in
+512-byte blocks, but a suffix of "c" specifies that size should be
+counted in characters (bytes) and a suffix of "k" specifes that
+size should be counted in 1024-byte blocks.
+
+=item C<-atime N>
+
+True if last-access time of file matches N (measured in days) (see
+below).
+
+=item C<-ctime N>
+
+True if last-changed time of file's inode matches N (measured in days,
+see below).
+
+=item C<-mtime N>
+
+True if last-modified time of file matches N (measured in days, see below).
+
+=item C<-newer FILE>
+
+True if last-modified time of file matches N.
+
+=item C<-print>
+
+Print out path of file (always true).
+
+=item C<-print0>
+
+Like -print, but terminates with \0 instead of \n.
+
+=item C<-exec OPTIONS ;>
+
+exec() the arguments in OPTIONS in a subprocess; any occurence of {} in
+OPTIONS will first be substituted with the path of the current
+file. Note that the command "rm" has been special-cased to use perl's
+unlink() function instead (as an optimization). The C<;> must be passed as
+a distinct argument, so it may need to be surrounded by whitespace and/or
+quoted from interpretation by the shell using a backslash (just as with
+using C<find(1)>).
+
+=item C<-ok OPTIONS ;>
+
+Like -exec, but first prompts user; if user's response does not begin
+with a y, skip the exec. The C<;> must be passed as
+a distinct argument, so it may need to be surrounded by whitespace and/or
+quoted from interpretation by the shell using a backslash (just as with
+using C<find(1)>).
+
+=item C<-eval EXPR ;>
+
+Has the perl script eval() the EXPR. The C<;> must be passed as
+a distinct argument, so it may need to be surrounded by whitespace and/or
+quoted from interpretation by the shell using a backslash (just as with
+using C<find(1)>).
+
+=item C<-ls>
+
+Simulates C<-exec ls -dils {} ;>
+
+=item C<-tar FILE>
+
+Adds current output to tar-format FILE.
+
+=item C<-cpio FILE>
+
+Adds current output to old-style cpio-format FILE.
+
+=item C<-ncpio FILE>
+
+Adds current output to "new"-style cpio-format FILE.
+
+=back
+
+Predicates which take a numeric argument N can come in three forms:
+
+ * N is prefixed with a +: match values greater than N
+ * N is prefixed with a -: match values less than N
+ * N is not prefixed with either + or -: match only values equal to N
+
+=head1 BUGS
+
+The -follow option doesn't really work yet, because File::Find doesn't
+support following symlinks.
