	New configuration statement for manipulating the environment.

	The "env" statement is now a compound statement. It can contain four
	substatements: "clear" to clear the environment, "keep" to retain
	certain variable while clearing it, "set" to set a variable, and
	"unset" to unset a variable or variables.

	Both "keep" and "unset" can take globbing pattern as their argument,
	in which case they affect all variable matching that pattern.

	The value part in the "set" statement is subject to variable expansion,
	e.g.

	   set "MANPATH=$MANPATH${MANPATH:+:}/usr/local/man"

	The support for the old one-line syntax of "env" is retained for
	backward compatibility.

	to the file, instead of overwriting it.

2019-05-31  Sergey Poznyakoff  <gray@gnu.org>

	Minor fix

	* tests/shell.at: Append to the outfile instead of overwriting it.

	Provide an option to run commands via sh -c

	The new flag "shell" instructs pies to run the command marked with it
	as '/bin/sh -c $command'. Alternative shell can be supplied ising the
	'program' statement.

	This is useful if the command line uses shell-specific features (command
	or variable expansion, redirection, pipes, etc.)

	This commit also fixes a bug in the 'env' statement handling: a single
	argument with embedded whitespaces was undergoing word splitting and
	thus incorrectly handled as multiple arguments.

	* NEWS: Document changes.
	* doc/pies.texi: Likewise.
	* src/comp.c (component_free): Free command.
	(component_finish): Split command into argv/argc as directed by the

2016-02-28  Sergey Poznyakoff  <gray@gnu.org>

	Synchronize changes in runlevel with configuration reloads

	State transition algorithm used this far could cause spurious component
	wakeups in some cases.  Consider the following scenario: being in
	runlevel N, the configuration is changed so that a component X is added
	at runlevel N.  Then a change to runlevel N+1 is initiated.  What happens
	then is that X is woken up (still being in runlevel N) and terminated
	shortly afterwards, upon entering runlevel N+1.

	To avoid this, configuration must be reloaded after runlevel changes.

	* src/ctl.c (res_runlevel): Don't initiate ACTION_RELOAD after
	setting the runlevel.

	to pies_pause.

2009-08-27  Sergey Poznyakoff  <gray@gnu.org.ua>

	Fix diagnostic and help messages.

	1. Option descriptions in `--help' output do not constitute
	   conceptual sentences. Therefore, they should not begin
	   with a capital letter, nor end with a final point.
	2. According to standards.texi, a diagnostic message in a
	   non-interactive program "should not begin with a capital letter
	   when it follows a program name and/or file name, because that
	   isn't the beginning of a sentence.  (The sentence conceptually
	   starts at the beginning of the line.)  Also, it should not end
	   with a period."
