+# Bash startup file for better control of project environment.
+#
+# To have better control over the environment of each analysis step (Make
+# recipe), besides having environment variables (directly included from
+# Make), it may also be useful to have a Bash startup file (this file). All
+# of the Makefiles set this file as the `BASH_ENV' environment variable, so
+# it is loaded into all the Make recipes within the project.
+#
+# The special `PROJECT_STATUS' environment variable is defined in every
+# top-level Makefile of the project. It defines the the state of the Make
+# that is calling this script. It can have three values:
+#
+# configure_basic
+# ---------------
+# When doing basic configuration, therefore the executed steps cannot
+# make any assumptions about the version of Bash (or any other
+# program). Therefore it is important for any step in this step to be
+# highly portable.
+#
+# configure_highlevel
+# -------------------
+# When building the higher-level programs, so the versions of the
+# most basic tools are set and you may safely assume certain
+# features.
+#
+# make
+# ----
+# When doing the project's analysis: all software have known
+# versions.
