This is a simple, dumb Wapp (https://wapp.tcl.tk) application that does nothing but log all requests it recieves to stdout, including the content of any POSTs, intended for debugging purposes. Writing it and this README was faster than finding whatever thing may already exist that does this job. A usual invocation might be: $ ./postplayground --server 8080 after making wapp.tcl available to [package require], perhaps by doing the moral equivalent of: $ cp /path/to/wapp/checkout/wapp.tcl /somewhere/in/tcl/modules/path/wapp-1.0.0.tm Recalling of course that /somewhere/in/tcl/modules/path may be *added* to Tcl's module path with something like: $ export TCL8_6_TM_PATH=/somewhere/in/tcl/modules/path
