* This software is in the public domain.
*
* -----------------
+ * 22-May-99 added environment substitutuion, enabled with -E switch.
+ * Andreas Arens <andras@cityweb.de>.
+ *
+ * 12-May-99 added a feature to read data to be sent from a file,
+ * if the send string starts with @. Idea from gpk <gpk@onramp.net>.
+ *
* added -T and -U option and \T and \U substitution to pass a phone
* number into chat script. Two are needed for some ISDN TA applications.
