19 I just realised that /usr/bin/jabref is a bash script, which says
20
21 ---------------
22 gjl_package=jabref
23 gjl_main="net.sf.jabref.JabRef"
24 source /usr/share/java-config-2/launcher/launcher.bash
25 ---------------
26
27 and launcher.bash contains the lines
28
29 ---snip-------
30 # Source package env
31 # ---------------------
32 gjl_user_env="${HOME}/.gentoo/java-config-2/launcher.d/${gjl_package}"
33 gjl_system_env="/etc/java-config-2/launcher.d/${gjl_package}"
34 if [[ -f "${gjl_user_env}" ]]; then
35 source "${gjl_user_env}"
36 elif [[ -f "${gjl_system_env}" ]]; then
37 source "${gjl_system_env}"
38 fi
39 ---end snip---
40
41 which makes me suspect that there is a way to give per-package
42 specifications. Is there documented anywhere?

44 Cheers,
