Sometimes it is neccessary to have an ebuild for software, which was not released yet.
This can be done by postfixing version number:
https://dev.gentoo.org/~ulm/pms/head/pms.html#x1-290003.2
zero or more of the suffixes _alpha, _beta, _pre, _rc or _p, which themselves may be followed by an optional integer. Suffix and integer count as separate version components.
nunit-3.0.0_alpha
nunit-3.0.0_beta
nunit-3.0.0_pre
nunit-3.0.0_pre_p20160101
nunit-3.0.0_pre_p20160101-r1
nunit-3.0.0_pre_alpha_p20160101
nunit-3.0.0_pre_alpha_p20160101-r1
nunit-3.0.0_rc1
nunit-3.0.0_rc2
nunit-3.0.0
I am unsure about ordering of "_pre_alpha" and "_alpha". For me it looks like _pre_alpfa will be preferred when two versions of ebuild exists, which mean that the above naming scheme is not very good (need to check this)
Also I am unsure about ordering of nunit-3.0.0 and nunit-3.0.0_p1 (looks like the latter supercedes the former, which is not correct)
