Description:  Reformats a fungal assembly for release.
Also creates contig and agp files.

Usage:  fungalrelease.sh in=<input file> out=<output file>

I/O parameters:
in=<file>           Input scaffolds.
out=<file>          Output scaffolds.
outc=<file>         Output contigs.
qfin=<file>         Optional quality scores input.
qfout=<file>        Optional quality scores output.
qfoutc=<file>       Optional contig quality scores output.
agp=<file>          Output AGP file.
legend=<file>       Output name legend file.
overwrite=f         (ow) Set to false to force the program to abort rather than
                    overwrite an existing file.

Processing parameters:
fastawrap=60        Wrap length for fasta lines.
tuc=t               Convert sequence to upper case.
baniupac=t          Crash on encountering a non-ACGTN base call.
mingap=10           Expand all gaps (Ns) to be at least this long.
mingapin=1          Only expand gaps that are at least this long.
sortcscaffolds=t    Sort scaffolds descending by length.
sortcontigs=f       Sort contigs descending by length.
renamescaffolds=t   Rename scaffolds to 'scaffold_#'.
scafnum=1           Number of first scaffold.
renamecontigs=f     Rename contigs to 'contig_#' instead of 'scafname_c#'.
contignum=1         Number of first contig; only used if renamecontigs=t.
minscaf=1           Only retain scaffolds at least this long.
mincontig=1         Only retain contigs at least this long.

Java Parameters:
-Xmx                This will set Java's memory usage, overriding autodetection.
                    -Xmx20g will specify 20 gigs of RAM, and -Xmx200m will specify 200 megs.
                    The max is typically 85% of physical memory.
-eoom               This flag will cause the process to exit if an
                    out-of-memory exception occurs.  Requires Java 8u92+.
-da                 Disable assertions.
