-# USAGE:

-#   esh <-h | -V>
-#
-# Process and evaluate an ESH template.
-#
-# ARGUMENTS:
-#   <input>        Path of the template file or "-" to read from STDIN.
-#   <variable>     Variable(s) specified as <name>=<value> to pass into the
-#                  template (the have higher priority than environment
-#                  variables).
-#
-# OPTIONS:
-#   -d             Don't evaluate template, just dump a shell script.
-#   -o <file>      Output file or "-" for STDOUT. Defaults to "-".
-#   -s <shell>     Command name or path of the shell to use for template
-#                  evaluation. It must not contain spaces.
-#                  Defaults to "/bin/sh".
-#   -h             Show this help message and exit.
-#   -V             Print version and exit.
-#
-# ENVIRONMENT:
-#   ESH_AWK        Command name of path of the awk program to use.
-#                  It must not contain spaces. Defaults to "awk".
-#   ESH_MAX_DEPTH  Maximum include depth. Defaults to 3.
-#   ESH_SHELL      Same as -s.
-#
-# EXIT STATUS:
-#    0             Clean exit, no error has encountered.
-#    1             Generic error.
-#   10             Invalid usage.
-#   11             ESH syntax error.
-#   12             Include error: file not found.
-#   13             Include error: exceeded max include depth (ESH_MAX_DEPTH).
-#
-# Please report bugs at <https://github.com/jirutka/esh/issues>.
