+mlocate (locate/updatedb implementation)
+
+mlocate is a locate/updatedb implementation. It keeps a database of all
+existing files and allows you to lookup files by name. The 'm' stands for
+"merging": updatedb reuses the existing database to avoid rereading most
+of the file system, which makes updatedb faster and does not trash the
+system caches as much as traditional locate implementations.
+
+This is the same "locate" that's in Slackware-current (and eventually 15.0).
+
+This conflicts with Slackware 14.2's slocate package! Before installing
+this, add slocate to /etc/slackpkg/blacklist and then:
+
+  # removepkg slocate
+
+It's also recommended to:
+
+  # rm -rf /var/lib/slocate /etc/updatedb.conf
+
+The locate database will be created daily, as a cron job. If you don't
+want to wait, you can create it manually:
+
+  # /etc/cron.daily/mlocate
+
+If you want to revert to Slackware's slocate, remove slocate from
+/etc/slackpkg/blacklist, then:
+
+  # removepkg mlocate
+  # rm -rf /var/lib/mlocate /etc/updatedb.conf
+  # slackpkg update
+  # slackpkg install slocate

+# Notes:
+# - This is intended to be 100% compatible with the mlocate in -current.
+# - mlocate and slocate can't read each others' database formats. Bummer.
+# - DOWNLOAD is upstream's site, but the file is identical to the one
+#   from Pat's source/ dir. I used upstream so the file won't disappear if
+#   Pat upgrades or changes his mind.
+# - mlocate on -current uses the slocate group (there's no mlocate group),
+#   so I do the same here.
+# - mlocate's database is about 40% larger than slocate's, on my build box.
+#   Not a real concern unless you're building a tiny embedded system.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
