in tcsh-6.14-r3.ebuild, pkg_postinst() { while read line; do einfo "${line}"; done <<EOF The default behaviour of tcsh has significantly changed starting from version 6.14-r1. In contrast to previous ebuilds, the amount of customisation to the default shell's behaviour has been reduced to a bare minimum (a customised prompt). If you rely on the customisations provided by previous ebuilds, you will have to copy over the relevant (now commented out) parts to your own ~/.tcshrc. Please check all tcsh-* files in /usr/share/tcsh-6.14-r2/example and include their behaviour in your own configuration files. The tcsh-complete file is not any longer sourced by the default system scripts. EOF } But the examples are really in /usr/share/doc/{$P}/examples and while this is sensible, it is not intuitive. I looked in /usr/local/share after not finding any /usr/share/tcsh-XXX, but had to find this page: http://bugs.gentoo.org/show_bug.cgi?id=119361 before finding the examples.
thanks, I fixed the url as you suggested
