Subject: Feature: Add -U/--under parameter to Featureless Make.
X-Git-Tag: 0.6.7~6
X-Git-Url: https://git.kevux.org/?a=commitdiff_plain;h=18b103849ffbaeb33c76191a50afc1e2a492c59f;p=fll

Feature: Add -U/--under parameter to Featureless Make.

I discovered that the data build directory customization is incomplete while working on the Kevux Tools TacocaT program.

A new parameter to specify a sub-directory within the data directory, called "under", represented by -U and --under is now added.
This provides the ability to change the "build" part of the "data/build" directory.
This can even be an empty string.

The fakefile documentation and specification is updated because this parameter must now be reserved and exposed to IKI expansion.
I have not yet done a thorough test of this feature and I will hopefully do this before the next release.
I have performed a basic test and I can now compile the TacocaT program easily using this parameter.
