Subject: Allow wish interpreter to be defined with TCLTK_PATH
X-Git-Tag: v1.5.2-rc0~38^2~3^2~4
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=e2a1bc67d321a0c03737179f331c39a52e7049d7;p=git.git

Allow wish interpreter to be defined with TCLTK_PATH

Makefile got one external option:
- TCLTK_PATH: the path to the Tcl/Tk interpreter.

Users (or build wrappers) may set this variable to the
location of the wish executable.
