+\description{
+\code{load_all} loads a package. It roughly simulates what happens
+when a package is installed and loaded with \code{\link[=library]{library()}}.
+}
+\details{
+Currently \code{load_all}:
+
+\itemize{
+\item Loads all data files in \code{data/}.  See \code{\link[=load_data]{load_data()}}
+for more details.
+
+\item Sources all R files in the R directory, storing results in
+environment that behaves like a regular package namespace. See
+below and \code{\link[=load_code]{load_code()}} for more details.
+
+\item Compiles any C, C++, or Fortran code in the \code{src/} directory
+and connects the generated DLL into R. See \code{\link[=compile_dll]{compile_dll()}}
+for more details.
+
+\item Runs \code{.onAttach()}, \code{.onLoad()} and \code{.onUnload()}
+functions at the correct times.
+
+\item If you use \pkg{testthat}, will load all test helpers so
+you can access them interactively. Devtools sets the
+\code{DEVTOOLS_LOAD} environment variable to \code{"true"} to
+let you check whether the helpers are run during package loading.
+
+}
+}
+\section{Namespaces}{
+
+
+The namespace environment \code{<namespace:pkgname>}, is a child of
+the imports environment, which has the name attribute
+\code{imports:pkgname}. It is in turn is a child of
+\code{<namespace:base>}, which is a child of the global environment.
+(There is also a copy of the base namespace that is a child of the empty
+environment.)
+
+The package environment \code{<package:pkgname>} is an ancestor of the
+global environment. Normally when loading a package, the objects
+listed as exports in the NAMESPACE file are copied from the namespace
+to the package environment. However, \code{load_all} by default will
+copy all objects (not just the ones listed as exports) to the package
+environment. This is useful during development because it makes all
+objects easy to access.
+
+To export only the objects listed as exports, use
+\code{export_all=FALSE}. This more closely simulates behavior when
+loading an installed package with \code{\link[=library]{library()}}, and can be
+useful for checking for missing exports.
+
+}
+
+\section{Shim files}{
+
+
+\code{load_all} also inserts shim functions into the imports environment
+of the laded package. It presently adds a replacement version of
+\code{system.file} which returns different paths from
+\code{base::system.file}. This is needed because installed and uninstalled
+package sources have different directory structures. Note that this is not
+a perfect replacement for \code{base::system.file}.
