+tzleap - leap-seconds.list from tzdb (zoneinfo)
+
+This package installs the leap-seconds.list file to the standard path
+expected by some software:
+
+    /usr/share/zoneinfo/leap-seconds.list 
+
+The IANA keeps the data and code used to create the Time Zone Database,
+("tz", "tzdb", "zoneinfo").
+
+    https://www.iana.org/time-zones
+
+This file comes from the commit for a tagged release from the
+maintainer's repo:
+
+    https://github.com/eggert/tz
+
+Slackware installs the current glibc-zoneinfo-* package, but does not
+include the leap-seconds.list file.

+# 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.
