SUMMARY: no change necessary in your project, this commit only involves changes in how already-existing software are built. Some handy options have also been added to the top-level project script and the copyright years have been updated. Until now, if the host's '/bin/sh' had conflicts with the Maneage environment, the configuration of Maneage would crash as soon as we entered the building of high-level software. The full scenario is described in the comments of the newly added 'reproduce/software/shell/prep-source.sh'. This is most relevant when building older Maneage'd project in newer environments. With this commit, the following changes were made to avoid the problem above: - Maneage edits the source code of all installed software to replace '/bin/sh' with Maneage's own shell before the programs are built. Through this, we were able to solve the problem described above. - The portable '#!/usr/bin/env sh' shebangs are now used at the start of the scripts that run during configure time so it uses the first available shell that it finds in its PATH (the system's before Dash is built), then Dash, and after Dash is built, Bash. - For TeXLive, since we don't install it from source, it was necessary to add the libraries necessary for the local '/bin/sh' in LD_LIBRARY_PATH. Some high-level options have been added to the './project' script to simplify certain operations: --keep-going: do not stop upon the first crash, but keep going on to build targets until all build-able targets have been built. This is very useful for debugging large pipelines and allows you to isolate the problematic part of your project. --highlight-all: equivalent to calling both '--highlight-new' & '--highlight-notes'.
