+execline is a (non-interactive) scripting language, like sh ; but its
+syntax is quite different from a traditional shell syntax. The
+execlineb program is meant to be used as an interpreter for a text
+file; the other commands are essentially useful inside an execlineb
+script.
+
+execline is as powerful as a shell: it features conditional loops,
+getopt-style option handling, filename globbing, and more. Meanwhile,
+its syntax is far more logic and predictable than the shell's syntax,
+and has no security issues.
+
+execline requires skalibs at build time but not at run time.
+
+execline installs into /command to match the skarnet.org examples.

+# 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.
