The LOCSMITH online documentation contains quite a lot of text and (hopefully) information.
But: Don't Panic! You do not need to read everything of this. The documentation
is not only a User's Guide, but also a technical documentation which is intended to make the programming of the Software transparent to those (including myself)
who want to further develop the code.
However, there are some things you should read in order to understand how LOCSMITH works and how you get your data into the program. I recommend to read the following sections:
The DIAGNOSTIC MESSAGES section could become important to you, since it describes the error messages and warnings LOCSMITH will return in case of problems. But I recommend not to look into these pages before the occurrence of an error... that could be too depressing ;-) (there are a lot of possible error messages in order to help you fix problems, but that does not mean that a lot of errors will actually occur!)
The PROGRAMS section contains descriptions of the calling sequence of each .m-file in the LOCSMITH package. You will not need most of these descriptions, because most routines are just subroutines.
