-#   Gradle start up script for POSIX generated by Gradle.
+##  Gradle start up script for UN*X
-#
+##
-#   Important for running:
-#
-#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
-#       noncompliant, but you have some other compliant shell such as ksh or
-#       bash, then to run this script, type that shell name before the whole
-#       command line, like:
-#
-#           ksh Gradle
-#
-#       Busybox and similar reduced shells will NOT work, because this script
-#       requires all of these POSIX shell features:
-#         * functions;
-#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
-#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
-#         * compound commands having a testable exit status, especially «case»;
-#         * various built-in commands including «command», «set», and «ulimit».
-#
-#   Important for patching:
-#
-#   (2) This script targets any POSIX shell, so it avoids extensions provided
-#       by Bash, Ksh, etc; in particular arrays are avoided.
-#
-#       The "traditional" practice of packing multiple parameters into a
-#       space-separated string is a well documented source of bugs and security
-#       problems, so this is (mostly) avoided, by progressively accumulating
-#       options in "$@", and eventually passing that to Java.
-#
-#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
-#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
-#       see the in-line comments for details.
-#
-#       There are tweaks for specific operating systems such as AIX, CygWin,
-#       Darwin, MinGW, and NonStop.
-#
-#   (3) This script is generated from the Groovy template
-#       https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
-#       within the Gradle project.

-/**
- * Stream class for reading BGZF block compressed files.  The caller can treat this file like any other InputStream.
- * It probably is not necessary to wrap this stream in a buffering stream, because there is internal buffering.
- * The advantage of BGZF over conventional GZip format is that BGZF allows for seeking without having to read the
- * entire file up to the location being sought.  Note that seeking is only possible if the input stream is seekable.
- * 
- * Note that this implementation is not synchronized. If multiple threads access an instance concurrently, it must be synchronized externally. 
- *
- * @see <a href="http://samtools.sourceforge.net/SAM1.pdf">http://samtools.sourceforge.net/SAM1.pdf</a> for details of BGZF file format.

- * Stream class for a file that is a series of gzip blocks (BGZF format). The caller just treats it as an
- * OutputStream, and under the covers a gzip block is written when the amount of uncompressed as-yet-unwritten
- * bytes reaches a threshold.
- *
- * The advantage of BGZF over conventional gzip is that BGZF allows for seeking without having to scan through
- * the entire file up to the position being sought.
- *
- * Note that the flush() method should not be called by client
- * unless you know what you're doing, because it forces a gzip block to be written even if the
- * number of buffered bytes has not reached threshold.  close(), on the other hand, must be called
- * when done writing in order to force the last gzip block to be written.
