22 // This file is derived from the old tkshell.c, and implements the Pltk init
23 // function. It can be loaded into any Tcl7.5 interpreter, and requires some
24 // .tcl library files to be in known places. Set your environment variables
25 // to make sure of this.
26 //
27 // Old changes see 'tkshell.c'. This file should be used _instead_ of
28 // tkshell.c, if building the 'libPltk.so' shared library for dynamic loading
29 // into Tcl.
