.SH "DESCRIPTION"
.sp
aragorn detects tRNA, mtRNA, and tmRNA genes\&. A minimum requirement is at least a 32 bit compiler architecture (variable types int and unsigned int are at least 4 bytes long)\&.
.sp
[\fIFILE\fR] is assumed to contain one or more sequences in FASTA format\&. Results of the search are printed to STDOUT\&. All switches are optional and case\-insensitive\&. Unless \-i is specified, tRNA genes containing introns are not detected\&.
