+# Since 'scons' doesn't use the traditional GNU installation with 'configure'
+# and 'make' it is installed manually using 'python'. After 'scons' is
+# installed, there is a file, '$(ildir)/scons/SCons/Platform/posix.py', that
+# contains several hard coded paths like '/usr/local'. This is bad because it
+# causes later problems in the installation of other programs (e.g., 'imfit').
+# As a consequence, at the end of the installation we replace the
+# '/usr/local' by the one Maneage uses: '$(idir)'. Only one of these paths
+# is replaced, the first one: '/usr/local'.

+# Unfortuantely SCons hard-codes its search PATH in its source (to
+# use POSIX operating system defaults)! So the only way to modify it
+# is to edit the source manually! Instead of using SED to replace a
+# fixed string, we are using AWK to replace the value. This is done
+# because in future versions, they may suddenly change the order, and
+# the fixed string won't match with SED. But with AWK, we can be
+# fully ignorant to their default value, and just change the value of
+# the known variable. Some technical notes:
+# - In the shell, the single quote is used to separate AWK's
+# environment from the shell, we are using '\47' instead of the
+# single quote.
+# - In Python (the source we are editing) indentation is
+# meaningful, but SPACE is a delimiter in AWK and AWK will
+# remove leading/trailing SPACE from its values. So we'll
+# manually inseart the necessary number of spaces before the
+# modified line.
