main () {
  declare expression="^EXAMPLE"
  declare -a args
  args=("$@")
  if (( $# == 0 )); then
    cat >&2 <<END
Usage: $0 [<args>...] [<expr>]

  args: Arguments to pass to man.
  expr: Command line argument to search for.
        Defaults to jump to the "EXAMPLE" section.

 Will open the man page in less and search for the specified
 expression at the beginning of lines.
 -> Just press "n" until you find what you are looking for!

xamples:

 • How does the -name option of find work?
   > $0 find -name

 • Can you give me some examples for using the find command?
   > $0 find

 • What does "%e" in printf() do?
   > $0 3 printf e
END
    return 1
  elif (( $# >= 2 )); then
    # Extract expression from last argument.
    expression="^[[:blank:]]*${args[-1]}"
    unset args[-1]
  fi
  PAGER="less -g -s '+/${expression}'" man "${args[@]}"
