+Analysis:
+Parseline (line) in parseabc.c checks the line for %%begintext using strcmp.
+Unfortunately, it does not find a match because the line also contains
+the word 'center'.
+
+Fix: replaced 
+if (strcmp(line,"%%begintext") == 0) {
+with
+if (strstr(line,"%%begintext") != NULL) {
+which returns the pointer to %%begintext in the line.
