-##  Gradle start up script for UN*X
-##
+#
+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   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.

- * Solves the Tag Assignment Problem. The tag assignment problem can be stated
- * thusly: Given a set of indices I in document d, and a set of tags T, find a
- * bijection f: T*⊂T → I*⊂I s.t. d[i..k] + t ∉ d[i'..(k + |t|)], ∀ i' ∈ I\{i},
- * ∀ k ∈ (i, |d|-|t|], where t ∈ T, i ∈ I. Maximize |I*|. This can be relaxed
- * to t=t[0] and ∀ k ∈ (i, i+K] for some fixed K, in most natural documents.
- *
- * More concretely, tags are typically two-character strings containing alpha-
- * numeric symbols. Documents are plaintext files. Indices are produced by a
- * search query of length N, i.e. the preceding N characters of every index i in
- * document d are identical. For characters proceeding d[i], all bets are off.
- * We can assume that P(d[i]|d[i-1]) has some structure for d~D. Ultimately, we
- * want a fast algorithm which maximizes the number of tagged document indices.
- *
- * Tags are used by the typist to select indices within a document. To select an
- * index, the typist starts by activating AceJump and searching for a character.
- * As soon as the first character is received, we begin to scan the document for
- * matching locations and assign as many valid tags as possible. When subsequent
- * characters are received, we refine the search results to match either:
- *
- *    1.) The plaintext query alone, or
- *    2.) The concatenation of plaintext query and partial tag
- *
- * The constraint in paragraph no. 1 tries to impose the following criteria:
- *
- *    1.) All valid key sequences will lead to a unique location in the document
- *    2.) All indices in the document will be reachable by a short key sequence
- *
- * If there is an insufficient number of two-character tags to cover every index
- * (which typically occurs when the user searches for a common character within
- * a long document), then we attempt to maximize the number of tags assigned to
- * document indices. The key is, all tags must be assigned as soon as possible,
- * i.e. as soon as the first character is received or whenever the user ceases
- * typing (at the very latest). Once assigned, a visible tag must never change
- * at any time during the selection process, so as not to confuse the user.
