Sortof. Consider this sequence of AAP output: 


Aap: uic -tr i18n setup_base.ui > build-FreeBSD4_9_RC/setup_base.h
Aap: echo "#include <klocale.h>" > build-FreeBSD4_9_RC/setup_base.cc
Aap: uic -tr tr2i18n -impl setup_base.h setup_base.ui > build-FreeBSD4_9_RC/
setup_base.cc.temp
Aap: sed -e "s,tr2i18n( \"\" ),QString::null,g" -e "s,tr2i18n( \"\"\, 
\"\" ),QString::null,g" -e "s,image\([0-9][0-9]*\)_data,img
\1_dbSelection_base,g" build-FreeBSD4_9_RC/setup_base.cc.temp >> 
build-FreeBSD4_9_RC/setup_base.cc
Aap: rm -rf build-FreeBSD4_9_RC/setup_base.cc.temp
Aap: echo "#include \""setup_base.moc"\"" >> build-FreeBSD4_9_RC/setup_base.cc
Aap:  g++   -I/usr/local/kde-3.2/include -I/usr/local/qt-3.2/include -I/usr/
local/include -I.    -MM build-FreeBSD4_9_RC/setup_base.cc > 
build-FreeBSD4_9_RC/build-FreeBSD4_9_RC/setup_base.cc.aap
build-FreeBSD4_9_RC/setup_base.cc:102: setup_base.moc: No such file or 
directory
Aap: Error in recipe "/home/adridg/aap/Exec-cvs/default.aap" line 148: :update 
failed for "setup_base.moc"


You can see that first a .h file is created. Then a C++ file is created, which 
contains the line #include "setup_base.moc". It _also_ contains the line 
#include "setup_base.h", but that file already exists in $BDIR (because my 
action to create the C++ file also explicitly :does the action to create 
the .h file). I'm a little worried about interactions between $BDIR and 
filenames #included in generated files, but that's not something to deal with 
here.

If I run aap -v, I see

Aap: Start :update "setup_base.moc"
Aap: Attempt :update "build-FreeBSD4_9_RC/setup_base.moc"
Aap: 1 - updating target "build-FreeBSD4_9_RC/setup_base.moc"
Aap: 1 - Do not know how to build "build-FreeBSD4_9_RC/setup_base.moc"
Aap: :update "build-FreeBSD4_9_RC/setup_base.moc" failed

wow, it's smart enough to know what to update, but somehow the update fails.  
There is a :rule %.moc : %.h, but apparently it's not invoked.

            If the door is ajar, can we fill it with door-jamb?
