 # clog
 Simple logging library for C
+
+If you want to save the logs to a file you can use `tee`:
+```
+someprogram | tee logfile.txt
+```
+
+The `-a` command line switch makes tee append to the file
+rather than truncating in overwriting it:
+```
+echo -e "\n---------\nSEPERATOR\n---------\n" >> logfile.txt
+someprogram | tee -a logfile.txt
+```
