The portage-bashrc-mv project is meant to be used with the gentoo portage system and serves two purposes.

  1. It provides support for an /etc/portage/bashrc.d directory in which you can define functions which are executed during emerge phases.
  2. It provides the following functionality in /etc/portage/bashrc.d
    • Support for an /etc/portage/package.cflags file (or directory) in which you can easily execute tasks or modify variables like CFLAGS on a per-package basis. This is similar to using /etc/portage/env but has a more convenient syntax for e.g. modifying CFLAGS. There is also a special flag filtering for non-GNU compilers (mainly clang). Moreover, pgo (profile-guided optimization) is supported.
    • Support for removing undesired .la files before installation
    • Support for removing undesired locales before installation
    • Support for CCACHE_* variables.
    • Output of time information and title bar if app-portage/portage-utils and app-shells/runtitle (the latter from the mv overlay) are installed.

See bashrc.d/README for more details.

For installation, just copy bashrc and bashrc.d into /etc/portage. There is also an ebuild in the mv repository (available by app-select/eselect-repository or app-portage/layman).
