+#!/bin/bash -e
+
+# This script is based in subsurface's packaging/windows/mxe-based-build.sh and
+# works in the same fashion. Building needs to be done in a directory out of
+# the source tree and, please, refer to said script for instructions on how to
+# build.
+#
+# Subsurface *MUST* have been built before running that script, as the importer
+# links against libsubsurface_corelib.a library.
+# Although is possible to build the latest git version of the importer against
+# whichever other version of subsurface, this should be avoided, and both
+# versions, subsurface and smtk-import should be the same.
+#
+# Flags and options:
+# -i (--installer): Packs a windows installer. This should always be used.
+# -t (--tag):       Defines which git version we want to build. Defaults to
+#                   latest. E.g. -t v4.6.4
+# -b (--build):     Values: debug or release. Defines the build we want to do.
+# -d (--dir):	    Specify a directory where a copy of the installer will be
+#                   placed. This is a *must* if the script runs in a VM, and
+#		    refers -usually- to a local dir mounted on the VM.
+#
+# Examples: (provided Subsurface has been previously cross built)
+#
+# smtk2ssrf-mxe-build.sh -i -t master
+# This will build an release installer of smtk2ssrf placed in a directory under
+# the win-build directory where it has been launched, named smtk-import. It will
+# build git latest master regardless of subsurface's cross built version.
+#
+# smtk2ssrf-mxe-build.sh -b debug
+# This will build *just* a windows binary (no packing) of the latest master.
+#
+# smtk2ssrf-mxe-build.sh -i -t v4.6.4 -b relase -d /mnt/data
+# As I'm building in a fedora-25 docker VM, this should bring up a release
+# installer of the v4.6.4 tag, and put a copy in my local mounted dir. In
+# fact this *should* fail to build because of portability issues in v4.6.4.
