+Welcome to Notmuch, a system for indexing, searching and tagging your email.
+
+We hope that the process of building and installing notmuch is quick
+and smooth so that you can soon be reading and processing your email
+more efficiently than ever.
+
+If anything goes wrong in this process, please do as much as you can
+to figure out what could be different on your machine compared to
+those of the notmuch developers. Then, please email those details to
+Carl Worth <cworth@cworth.org> so that we can hopefully make future
+versions of notmuch easier for you to use.
+
+We'll now investigate your system to find verify that various software
+components that notmuch relies on are available.

+install all of the dependencies with the following simple command
+line:
+
+	sudo apt-get install libxapian-dev libgmime-2.4-dev libtalloc-dev
+
+On other systems, a similar command can be used, but the details of the 
+package names may be different, (such as "devel" in place of "dev").

+Note: the pkg-config program is not available. Both this configure

+compilation flags required to link against the various libraries
+needed by notmuch. It's possible you simply need to install pkg-config
+with a command such as:
+
+	sudo apt-get install pkg-config
+
+But if pkg-config is not available for your system, then you will need
+to manually edit the notmuch Makefile to set NOTMUCH_CFLAGS and
+NOTMUCH_LDFLAGS to the correct values without calling pkg-config.
