.B -h N, --extend-heap-by=N
Specify the size of heap extension by the brk() system call.
The default size is 4K Byte. You may specify the value in the
following format:
<digit>{k|K|m|M|g|G}
e.g.:
10k for 10Kibyte, 100M for 100Mibyte, 1G for 1Gibyte
The default size is 4K Byte. \fIN\fR accepts the following format:
.br
.RS 10
<digits>{k|K|m|M|g|G}
.br
e.g.: 10k means 10Kibyte, 100M 100Mibyte, 1G 1Gibyte

.RS 7
In certain applications, such as miniFE, specifying "-h 12M" improves
performance.

.B -s P,[M], --stack-premap=P,[M]
Pre-map \fIP\fR bytes of stack when creating a process. 2Mibyte is
used when not specified. And set the max size of stack to \fIM\fR
bytes. Both of them accept the following format:
.br
.RS 10
<digits>{k|K|m|M|g|G}
