+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."
+
+        Affected files:
+
+        * pies/pies.c
+        * pies/progman.c
+
+2009-06-17  Sergey Poznyakoff  <gray@gnu.org.ua>
+
+        Bugfixes.
+
+        * pies/pies.c (main): Change main loop to do..while,
+        otherwise a signal arriving before entering the loop
+        might cause the program to terminate.
+
+2009-06-14  Sergey Poznyakoff  <gray@gnu.org.ua>
+
+        Fix and improve termination actions.
+
+        * pies/pies.h (MAX_RETURN_CODE): Remove.
+        (STATUS_SIG_BIT, STATUS_CODE): New defines
+        (struct action): New fields next, nstat, status, command.
+        (struct component): Keep singly-linked list of termination
+        actions.
+        * pies/progman.c (run_command): New function.
+        (progman_cleanup): Redo iteration over termination actions.
+        * pies/pies.c (return_code_cfg_param): Pass offsets in
+        struct component.
+        (create_action): Accept signal numbers (SIG.* or SIG\+[0-9]+)
+        in tag.

+
+2009-06-04  Sergey Poznyakoff  <gray@gnu.org.ua>
+
+        MeTA1-related improvements.

+
+2009-05-13  Sergey Poznyakoff  <gray@gnu.org.ua>
+
+        Minor change
+
+        * pies/progman.c: Use _exit in child processes.  This
+        is a work over a fault in MU design: it registers
+        the pidfile removal function via atexit.
